Not in my experience. They just regurgitate code, and juniors don’t know if/why it’s good or bad and consequently can’t field questions on their PR.
“It’s what the LLM said.” - Great. Now go learn it and do it again yourself.

In my experience it is the very rare junior dev that can learn what's good or bad about a given design on their own. Either they needed to be paired with a sr dev to look at things and explain why they might not want to something a given way, or they needed to wind up having to fix the mess they made when their code breaks something. AI doesn't change that.
I can't count how many seniors have forgotten what it means to understand the code they're merging since AI coding tools became popular. So long as businesses only value quantity the odds are stacked against juniors.
If people use AI to generate code they don't understand, that will bite them. But it's an incredibly tool for explaining code and teaching you boring, rote incantations.
