Brian Eno, Terry Riley, and John Cage are names that come close to doing what you are describing. The idea of “generative” or “stochastic” or “aleotoric” music has been around for longer than this current AI boom has.

I also found this fascinating bit of music on wiki:

viral symphOny is a collaborative electronic noise music symphony created by the postconceptual artist Joseph Nechvatal. It was created between the years 2006 and 2008 using custom artificial life C++ software based on the viral phenomenon model.

There are possibilities, but there are 99 lazy and uncreative people who just want to press the “make music now” button for every 1 person that wants to spend hours building and training their own models/sequences. (Those 99 have absolutely ruined the lofi/study beats on YouTube…)
