>Can LLM actually create or only regurgitate content.

Contrary to what others say, LLMs can create content. If you have a private repo you can ask the LLM to look at it and answer questions based on that. You can also have it write extra code. Both of these are examples of something that did not exist before.

In terms of gamefaqs, I could theoretically see an LLM play a game and based on that write about the game. This is theoretical, because currently LLMs are nowhere near capable enough to play video games.

It will remain in their scraped data so they can keep including it in their later training datasets if they wish. However it won't be able to do live internet searches anymore. And it will not generate new content of course. Especially not based on games released after the site codes down so it doesn't know. Though it could of course correlate data from other sources that talk about the game in question.

They cannot create original content.
