Both big rig trailer repair shops I mentioned did rubber torsion axle service of all sizes. Torsion axles have other parts that aren't rubber. However the OP didn't say the trailer was squatting more now.
Granted single axle trailer tires don't side scrub going around corners but a single axle tube or the spindle (torsion or std leaf spring axles) can bend when hitting a curb at 5 mpg.
At that speed usually a cut sidewall and bent rim damage from the curb can be normal.
Construction of a Torsion axle does not lend it's self as a good candidate for straightening without some compromise to the axle.
If the bend is at the stub, one could attempt to straighten or even replace the stub.
If bend is in the arm I suspect there is other additional hidden damage with the solid square steel in the center of the rubber which isn't going to be easy or reliable.
There is a lot of strain/stress where the arm attaches to the square steel, bending it out of shape then trying to bend it back into place can further weaken and distort the material.
You can't use heat anywhere near the rubber, heat will destroy the rubber in the tube so all manipulation must be done cold and doing so does distort the steel as it will never go back exactly the way it was.
I suspect if one contacted say Dexter and asked for technical assistance for their input I highly doubt they would recommend attempting to straighten a torsion axle (and not because they would make a sale)..
Interestingly enough, looking at Dexters Torflex info, their 5 bolt torflex is rated up to 4,100 lbs but that still means up 900 lbs will have to rest on the hitch.. OPs setup is most likely overloaded in spite of what they think..
