I don't think a delivery can be both "illegal" and a "no pitch". So maybe that's where the first hint is. I think a quick pitch should be ruled illegal, and if the batter decides to swing anyway, that makes it legal.

But if there's a "no pitch" call, I think everything should be re-set to how it was prior to that no pitch ever happening.

Since the BU made both calls, he confused everybody possibly including himself.

I'd say "do over".

You can't "do over" the IP. Once PU said "Illegal" you've got a ball on the batter.
