This hasn't yet been decided, as I pointed out above. The courts have indicated that push button LLM output is not copyrightable, but haven't said anything about larger orchestrations of multiple agents operating over hours or days to produce something with direction from a human.
Given that photographs are copyrightable, I wouldn't hold my breath on projects like this being deemed ineligible for copyright.
This project has zero chance of being eligible for copyright:
> Nearly all of the code, the design docs, and this README were written by Claude
The only way courts will deem LLM output to be copyrightable is if there is substantial human input. Just orchestrating agents won't be enough.
