So I agree that leaving an LLM churning for a week or two and then claiming that you have a product to sell is tenuous, but I disagree that one can't both use an LLM _and_ understand the solution - it just takes active participation towards that result.
Whilst there's no remuneration involved, I view projects I put up on github (that I also tell other people about) in the same light - so, for example, the largely-ai-written https://github.com/fluffynuts/nestray, whilst designed to scratch an itch of mine, may be useful for others because I've aimed at some level of genericism. Is it a perfect product? NO! But it does what I want, and probably what someone else might want with respect to showing email notifications without requiring any account access (simply reads from local Thunderbird files)
