Another point is tat I think current LLMs are arguably conscious. I am not saying they are but I am open to the possibility as human brains are physical systems that are conscious so there is no reason other conscious physical systems might not exist. In that light, or even otherwise, I think if we avoid heavy handed prompting or micromanaging, the AI itself has its own ways of thought, tics and style. So in that sense we can cite the AI itself as part composer.
