I agree that something needs to change at the organisation level in your case, but i think it's hiring and promotion. This "developer IT" stuff is part of a developer's job.

If you are recruiting seniors who don't know this stuff, stop, and if you are promoting juniors to senior before they've learned this stuff, stop.
