I'd argue that this is neither down to the programming language nor LLM used, but down to your own company's requirements, testing, and code review practices - but you did point the latter out so you're aware of it. I think the only thing you realistically can try to do is slow down. But it's also a trap I fall into myself - I don't usually thoroughly review my own merge requests because I wrote them, but now that LLMs generate them I don't review my code thoroughly either, and some issues have fallen through. Nothing critical, just stuff that, if someone asked me to review it, I'd flag up as something that could be polished a bit.
