Yes it does depend on the circumstances. You are free to waste your own time to try this at the copyright office, but in my opinion, this project's 100% LLM output where the human element is just writing prompts and steering the LLM is the same circumstance as my linked case where the human prompted Midjourney 624 times before producing the image the human deemed acceptable. The copyright office has this to say:
