Perhaps the county should just ban the burning of fool fuels. If its causing do many local deaths then surely that's the logical first step? Or would that just be political suicide?
But the companies, according to the lawsuit, knowingly and recklessly hid the negative externalities (CO2 emissions and hence global warming) from public scrutiny. These externalities potentially impact everyone, no matter how much oil they actually consumed or how much they benefited from society's oil consumption. The county does not have to ban oil (which it wouldn't be empowered to, anyway) to make that point. You don't have to agree with it, but the arguments you have brought up do not address the complaint that plaintiffs have brought here.
No, they paid for the direct results, i.e. heating oil, gasoline. The externalities that result include having a functional society where millions of people don't die every year due to the weather, where innovative goods (many of which are produced using large amounts of oil) can be produced anywhere in the world and still end up on a store shelf very close to you (or even delivered), and where the majority of people are freed up from having to produce their own food supply. Whereas a few deaths are countable (and the connection from oil production to these specific deaths is highly specious), the positive benefits of oil and electricity are so massive and so embedded and crucial to society that they are literally incalculable.
Further, the amount paid is massively reduced due to the incredibly efficient global infrastructure dedicated to producing, refining and transporting oil, thanks (in part) to Exxon, BP, Shell, etc. Instead of paying $60 for a gasoline fillup, imagine the costs of finding oil-producing land, independently drilling for oil and personally refining it into gasoline. The fact that you don't have to do any of that, is the true "externality" that you've benefitted from, but no, you have not paid for.
Overall, the quality of life for most people at the moment is certainly higher than it would have been if oil has never been developed as a natural resource. But the risk of unmitigated climate change (which largely is due to humanity's consumption of fossil fuels) is that this equation will shift in the coming years and the use of oil, coal, etc. will turn out to have had a net negative impact on human quality of life.
They are suing today, it hasn't even happened yet, and you're lacking proof it will. "Might" is the word you should be using, not "will." "Might not" is a lot more probable, however.
There's a summary paper here that explores the data and shows this to be true:

The analysis is then extended to some global response indicators of extreme meteorological events, namely natural disasters, floods, droughts, ecosystem productivity and yields of the four main crops (maize, rice, soybean and wheat). None of these response indicators show a clear positive trend of extreme events
There are other indicators you could use but they also don't show any crisis of extreme weather, often the opposite. Examples:
- Wildfire burn acreage is drastically down over the past 100 years.
- Hurricanes are in decline, both in frequency and energy.
- Rainfall is also down slightly.
You can google those claims to find them if you like because the datasets are all public, except maybe the third which is a bit obscure so I'll give it here:

the small- and medium-size precipitation systems both exhibit significant decreases during 2001–2020 with trends at −1.13 and −2 mm/h per century, respectively. The large-size precipitation systems exhibit nonsignificant increasing trends during 2001–2020.
These quotes are from the IPCCC (which represents the consensus of thousands of climate scientists) sixth assessment report from 2021:
"The frequency and intensity of hot extremes (including heatwaves) have increased, and those of cold extremes have decreased on the global scale since 1950 (virtually certain). This also applies at regional scale, with more than 80% of AR6 regions1showing similar changes assessed to be at least likely."
"The frequency and intensity of heavy precipitation events have likely increased at the global scale over a majority of land regions with good observational coverage. Heavy precipitation has likely increased on the continental scale over three continents: North America, Europe, and Asia. Regional increases in the frequency and/or intensity of heavy precipitation have been observed with at least medium confidence for nearly half of AR6 regions, […]"
"More regions are affected by increases in agricultural and ecological droughts with increasing global warming (high confidence)."
"The average and maximum rain rates associated with tropical cyclones (TCs), extratropical cyclones and atmospheric rivers across the globe, and severe convective storms in some regions, increase in a warming world (high confidence)."

This stuff is complex, as is correctly interpreting the available data. But sure, go with the opinion of four random Italian dudes over the consensus of literally thousands of subject matter experts.
