i'd say reddit is a pretty great example, twitter, even instagram or facebook comments, where bot generated traffic and comments are a norm.

you have plenty of bot or "AI/LLM" generated content, that is consumed -- up to and including things like "news".

as for the comment about movies, i'm confused -- CGI has been a thing for a long time, and "AI" has been used to convey aging or how a person might look given some conditions, on screen, as well as a whole host of things.

while this might not be an LLM, it is certainly computer generated, predictive, and artificially generated.
