I assume you are implying that LLM generated projects don't mean bad quality. That's true. At same time we all know what this means. Plausibly looking projects that might even work but have little human oversight. There are so many of them It's really difficult to know. I don't want to depend on such code and I bet neither do most programmers. Why? Because by then you might as well vibe the library yourself and be the one who does the oversight.
I might be wrong but I doubt that people on Codeberg are against use of LLMs that make the projects better. Like finding security leaks. What these rules are aimed at are hosting of endless vibe coded projects that are just copy of each other.
