That sucks,

Did they actually do the alignment? Sounds like the toe is off.
As for the tires those Kumhos those are some greasy tires new. If they non directional try putting them on the other side. If that doesn't work a nice burn out would take that layer of oil off the threads.

Our lsd are really sensitive with low psi tires that must have been the reason why it freaked out.

Besides that nothing much you can do. Eventually they will even out.
There's is always hope that putting new tires up front can fix it, but eh maybe.
