Hard enough to be an intentional foul-probably not flagrant.

What's the call-HS Fed rules? Can it be a technical on a dead ball even though it happened so fast the travel wasn't called yet?

Correct would be to first call the traveling violation. Now you remember that the ball is dead at the time of the violation, not when the whistle blows for the official to then make the call. Therefore, the contact is during a dead ball and if, as you say, the contact was severe enough to be called an intentional foul then you have an intentional technical foul.
