As most others I’m also very doubtful of making this a worthwhile venture. I hope OP didn’t pay too much and makes this a chill project.
I see 2 additional paths:
1) I have no knowledge, but how does the let the crawlers pay work? Could a site like css-tricks with a lot of backlinks make money on that ? Or do LLMs have enough free content available
2) He could make this an anti-llm design website.
