In my experience, most coding work is on established code bases. There's that well thought out senior engineer phase at the start of each project, but the vast majority of future work starts with grokking the existing code base. I don't think we'll see much of an impact of LLM-generated code until these systems are trained on the code and the existing user and dev documentation of the project itself. As for jr. engineer impact and prospective candidates, I'd say virtually zero.
