I mean they would prohibit all vital operations of these companies in China. What would Apple do if China will give them a Huawei treatment?
They wouldn't even be able to move away from China, if their Chinese suppliers would be told to cease doing business with Apple globally.
Pretty much every globally prominent company dealing with light industries, manufacturing, electronics has some things in their products which they cannot reasonably expect to get elsewhere but in/from China.
Second to that: check what you saw in the previous half of the year. A lot of living essentials are made almost solely in China. Would US elites be ready to deal with angry unwashed masses who, with some help, and incitement, would go torch their houses because they can't get not only their new Iphone, but basic medicines, clothing, car parts, basic household goods, widgets for their businesses, and such?
Unless Americans are ready for that, they can't fight China, and the people in Beijing know it very well.

Well, all those people would instantly be out of a job for one. What Huawei factories in the US are being shut down? It's one thing to lose market access, it's another to lose jobs.
> Pretty much every globally prominent company dealing with light industries, manufacturing, electronics has some things in their products which they cannot reasonably expect to get elsewhere but in/from China.
Cheap is a better word here. There is not a single item in China that can't be replicated elsewhere in the world for consumer products.
> A lot of living essentials are made almost solely in China.
Because of cheapness, not because they can't be created elsewhere. Many countries can create these goods, including the U.S.
> Unless Americans are ready for that, they can't fight China, and the people in Beijing know it very well.
Americans might not be "ready" but they can definitely decouple with China if push comes to shove.
Sell to another country at lower prices, and less profit than the can get from the US?

It's worth noting that most of the wiki article is basically a list of counter-examples that proved that statement false. There have been a half-dozen wars between McDonald's-havers.
It should also be noted that there were plenty of experts who would tell you that the world is now too economically intertwined to be able to support any major war between major powers... in 1914. Economic integration preventing global conflict has been disproven time and again in history.
I don't think it'd play out like that. It's been a few generations, but Americans have experience with wartime rationing that was far more extreme. They didn't riot and demand a peace treaty with Hilter and Tojo, so they could could get the consumer goods they had been used to having.

But, I don't see any US president standing for it before the election, or at least attempting to sell it to his electorate/funders, unless pretty much a hot war is happening.
USA was the biggest industrial power by late thirties, and I think no country would've stood for Germany in the open on the global arena by then. The situation is more than a bit different now.
Be hopeful that the politicians will be as logical as you are.
I don't think it would be a hard to sell the American public on some kind of rationing if Beijing suddenly embargoes the US in a way that necessitated it. Given the economic dependencies that you cite, I think a US-initiated decoupling would likely proceed slowly enough to not cause critical disruption, just higher prices.
