For instance, if the extra dimensions that it predicts exist, physicists expect black holes and massive string-balls to be produced in LHC collisions.

Yes, I was thinking about that too. So once they discover the graviton particle actually does exist it should be evidence for at least another dimension?
Not necessarily. There are other models that predict the existence of the graviton. For instance, Loop Quantum Gravity doesn't require extra dimensions to be consistent, but because it is a quantum gravity theory, it predicts the graviton.
