You're missing the existence of technology that allows anyone to create superficially plausible but ultimately made-up anecdotes for posting to public forums, all just to create cover for a few posts here and there mixing in advertising for a vaguely-related product or service. (Or even just to build karma for a voting ring.)
Currently, you can still sometimes sniff out such content based on the writing style, but in the future you'd have to be an expert on the exact thing they claim expertise in, and even then you could be left wondering whether they're just an expert in a slightly different area instead of making it all up.
No, now that LLMs are invented, a lot more people lying on the Internet have started to do so convincingly, so they also do it more often. Previously, when somebody was using all the right lingo to signal expert status, they might've been a lying expert or an honest expert, but they probably weren't some lying rando, because then they wouldn't even have thought of using those words in that context. But now LLMs can paper over that deficit, so all the lying randos who previously couldn't pretend to be an expert are now doing so somewhat successfully, and there are a lot of lying randos.
It's not "LLM bad" — it's "LLM good, some people bad, bad people use LLM to get better at bad things."
