Maybe Jesus will kiss me on the cheek and I'll be able to perfectly render GTA 6 rtx in my mind.
But maybe we live in reality.
(science side of my opnion, LLMs are almost the same algorithm as a search engine in the background, making true novelty impossible. No one has yet created another novel OS like you describe for the AI companied to scrape, repackage, and resell yet, so its impossible for the LLMs to output such an OS.)
(The other other side of it is what do you even mean by a novel, stripped down, adapted OS? Like what has FOSS been developing for the past 40 years lmao? Anyone in the OS dev world knows usually the system itself is the most optimised part of the whole computer. Let's shit on uncompressed 140gig games if we want to shit on someone)
