It's funny, I have the same problem, but with subject matter expertise. I work with internal PR people and they clearly have shifted their writing efforts to be AI-assisted or even AI-driven. Now I as the SME get these AI-written blog posts and press releases and I spend a far more time on getting all the hallucinations out of these texts.
It's an effort inversion, too - time spent correcting the PR-people's errors has tripled or quadrupled. They're supposed to assist me, not the other way around. I'm not the press release writer here.
And of course they don't 'learn' like your junior engineers - it's always AI, it's always different hallucinations.
P.S.: And yes I've raised this internally with our leadership - at this rate we'll have 50% of the PR people next year, they're making themselves unemployed. I don't need a middleman who's job it is to copy-paste my email into ChatGPT, then send me the output; I can do that myself.
