An LLM doesn't do anything on its own. One needs to make the choice to build something, make choices about how it's built, and make decisions on how it should work. The LLM makes the output of those decisions, but in the end it's just one of the tools that was used to make a part of the system that was built.

replyYou prompted, the LLM made. The output of the LLM is not eligible for copyright.
You can perhaps copyright the prompt. That you did make.
