There's a trend where people go around claiming they built something and just happen to conveniently omit everywhere that everything was "built" using an LLM and the author doesn't even understand what the code does. That's the crux of my objection.

FWIW I agree with your post and perhaps we need a separate name for people who just instructed an LLM to build something, but then took the trouble to understand how the thing actually works.

It seems to me that this is not the case here. The author used LLM to build the whole thing and left it at that. Which is completely fair, I'd do the same if I just wanted to scratch an itch with the minimal amount of effort, but then I wouldn't go around claiming "I built it".
