Are base runners always protected on a illegal pitch?

#3 Illegal pitch batter does put ball in play. Pending result of ball in play Offense chooses result of play or ball on batter baserunners advance.

Can't be a pick off play on an illegal pitch because it's a dead ball once catcher has it.

My experience is NSA only, but a assume this would apply universally??

#1 Just semantics, but not LBR violation. Simply leaving early violation.

#3 Coach MAY or MAY NOT have an option. "If the illegal pitch is hit and all runners including the batter-runner , advance one base, the play stands."
* This could lead to a situation where, for example, the D could get a double play and the O would have to live with it. - Is this different in other rule sets?
