How does an open bolt SMG with a fixed firing pin prevent primer strikes if a round jams with the bolt out of battery?

it doesn't
this is a problem inherent with open bolt SMGs, but is tolerated since they're so cheap to make
The firing pin isn't in position directly over the primer yet.
Normally it is not lined up with the firing pin. Only when the bullet is in the chamber is the bullet lined up for the firing pin.
It doesn't. But on a straight blowback design especially on an open bolt gun it's incredibly uncommon for a round to get stuck in the chamber except for a failure of the round itself.
