If one person in the hiring chain knows German, you're out of luck. And more than likely, if they can't find a university, you are probably lying. Universities are big, kinda hard to not be able to find one.
You should not lie on your resume, but if you're going to lie, just find a way to make it harder to verify. Presumably the for-profit schools that got shut down in the last few years would be hard to check with. Obviously they aren't accredited, but that's not your fault. It'd be, at least, a believable lie.
The point is if they knew German they’d get the joke... you’re not trying to lie. You’re trying to get past the crazy HR driven mandate that EVERYONE have a 4 year degree, even when it has zero relevance to the job.
