But it does. It predicts extra dimensions and it predicts supersymmetry. However it might be that these are only visible beyond our achievable energy levels such that we cannot verify them. The goal would then be to find what other indirect (as in not actually observing the strings) feature string theory predicts, that is hopefully within our reach, and verify that.
"Make the effort" is like complaining that cancer hasn't been cured because people just haven't tried hard enough. It's one of the hardest intellectual problems the human race has ever faced.
The "effor" has nothing to do with cancer and has a lot to do with the REAL WORLD we live in. Physics either talks about REAL experiments or is otherwise void of value.
There are lots of speculative nonsensical theories which can be brought up and have no relation to the real world. As long as they are not falsifiable, they are not Physics.
The potential for discovering supersymmetry through the LHC was indeed minimal. There is nothing disingenuous about that.
The LHC is conducting a vast number of experiments on a vast array of topics. Perhaps the main goal was to uncover the Higgs boson, which unlike supersymmetry could be disproved if it wasn't found by the LHC.

It's an analogy...

They are theoretical physics, though.
Again, I don't know what your overall point is. That we should just all give up and end theoretical physics right now for good?
The bottom line is that if you think people aren't putting in the effort, you're wrong. That's my my point here.
