I guess the point you're trying to make is that apps developed by LLMs don't need to be all that bad, but the problem here is that you can't know who does their due diligence with auditing their own code and who doesn't, and you can't expect potential users to do it either. Especially not when similar apps get published at increasingly faster rates.

LLMs also helps inexperienced engineers (or people who do not have any own software engineering skills themselves) to write horrible code in less time.

Of course you also can't trust everything human developers publish either, but the issue is amplified by LLMs.
