It makes you less valuable and your job less secure because as LLMs improve, the level of knowledge/skill required goes down, thus putting more people at the level of "good enough", which is generally what companies optimize for over time with regards to hiring (least amount for good enough).

I'm sick of seeing this argument because it's not as persuasive as you think. If you were incapable of doing it before, why would I ever trust that you could properly evaluate the result? Even if I did, it's still like saying, "I never would've been able to do this project without a subordinate that knew how to do it, now look at me!" Okay? So why would I choose you when it sounds like I could pick anyone with basic programming knowledge to manage the subordinate since I clearly don't need someone with the know-how to do the thing, just someone capable of wrangling a coding agent? Might as well get the cheapest college CS graduate I can find.
