We've seen that such punches are powerful enough to break Susanoo, meaning that it does considerable damage. She may be immune to ninjutsu, but as Guy demonstrated, taijutsu works just fine.

Judging by the angle, Sakura was in her Byakugan blindspot, hence she didn't see it coming. And it was already established twice that she didn't even consider her a threat worth taking out. So no, it's actually a very reasonable action that worked within the established framework.
