There are no theories left that LHC, or any collider we could build, can test. Strings are right out. Nobody has offered any clue as to how to make a prediction that could be tested with possible equipment. That does not mean none ever will, but it does not seem to be their focus. Physics departments like string theorists because they come with no equipment budget.
