The approach that Google appears to have taken, which is to assume that the top-ranked part of its current search index is a sensible knowledge base, may have been true some years ago, but definitely isn't now: for whatever reasons, it's now 33% spam, 33% clickbait/propaganda, with the rest being equally divided between what could be called "truths" and miscellaneous detritus.
To me, it seems that returning to the concept that search results should at least reflect a broad consensus of what is true is a necessary first step for Google. As part of that, learning to flag obvious trolling, clickbait and bad-faith content is paramount. And then, maybe then, they can start touting their LLM benefits. But until the realities of the Internet are taken into account (i.e.: it's 80% spam!), any "we offer automated answers!" play is doomed.
