In an otherwise 'empty' universe, would two protons randomly placed in that universe eventually collide due to gravity?

No - the electrostatic repulsion due to the protons having the same charge would prevent them from coming into contact.

Even if you threw them at each other really hard, they would either deflect off each other, or you would end up with some resulting particles that are no longer two protons, as in the LHC.
