It's appropriate to think this way with LLM output because LLMs are still terrible some significant portion of the time. If you don't actually know what you're doing, you have no way to distinguish between their output being correct or their output being able to pass the tests you can think of.

As a software developer, your job is to understand code and business constraints so you can solve problems the way most appropriate for the situation. If you aren't actually keeping up with those constraints as they change through time, you're not doing your job. And yeah, that's a kind of fraud. Maybe it's more on yourself than your employer most of the time, but... It's your job. If you don't want to do it, maybe it's more respectful of your own time, energy, and humanity to move on.
