Not that I know of. English has the very common word “can’t”, and Kant is at least as far from being snicker-worthy. I suppose a viral video could change that, but AFAIK that hasn’t happened.
Also, as janbb mentioned, I’d be surprised if any US public schools (except maybe in someplace like Cambridge MA where they actually fund them to be good) actually had a lecture on Kant.
On the other hand, I have heard of some US teachers having peculiar ideas of how to pronounce some name, and students who know better, laughing at them a lot for it, so I expect it may have happened somewhere, perhaps in a private prep school somewhere that actually does mention Kant.
