I've been contemplating this a lot lately, as I just did code review on a system that was moving all the AWS infrastructure into CDK, and it was very clear the person doing it was using an LLM which created a really complicated, over engineered solution to everything. I basically rewrote the entire thing (still pairing with Claude), and it's now much simpler and easier to follow.

So I think for developers that have deep experience with systems LLMs are great -- I did a huge migration in a few weeks that probably would have taken many months or even half a year before. But I worry that people that don't really know what's going on will end up with a horrible mess of infra code.
