I mean, you're basically LLM-washing other people's code, then. All those UI components that other people wrote and at least expected attribution may not be libraries anymore, sure. But you've basically just copied and maybe lightly modified that code into your project and then slapped a sticker on it saying "mine." If you did that manually with open source code, you'd be in violation of the attribution terms almost all the licenses have in common. But somehow it's okay if the computer does it for you?
It is a gray area. What if you took Qt, removed macros, replaced anchoring with css for alignment, took all widget properties out into an entity component system and called it ET, could Trolltech complain? It is an entirely new design and nothing like they built. A ship of Theseus if you will.
