Does one commit an act of disbelief by seeking revival from the "Medic" character in a video game, while knowing that revival belongs to Allah alone?

It is not permissible to play with toys that claim the ability to revive the dead or other such divine attributes. While playing with them is forbidden, merely playing or uttering those words does not constitute disbelief, as long as the player believes in the futility of what they imply and that Allah alone is capable of reviving the dead.
