I take your point, but as the OP said the socket in the end of the axle has rounded off, that suggests perhaps the steel isn't has hard as it could be.

I'd try a little heat if possible..
Try tightening a fraction just the breakthe corrosion/sticktion often you can then loosen easier.
I'd also try bashing in a sacrificial oversize torx. If it's chewed up it must be softer than the tool. Failing that, crank off and drill/take to local engineers.

The sacrificial torx trick only works on soft metal. If the metal is hard enough to deform the torx, it will have no strength left to turn the pedal axel. Also, I doubt that the pedal socket is damaged, I bet it is the allen key. @OP - Photos please.

I'd go with that, but the AP did state that the socket was damaged.
Cheap tools of cheese are the worst value thing ever. One of the best things I ever did was bought a set of reassuringly expensive Hex key bits of suitably hard material.

It is possible to induction harden small sections of material, so the fact that one small section used as a bearing surface is hard does not mean that it is all hard. I was lucky enough to have a tour of the Cummins turbocharger factory years ago, so I've seen turbocharger spindles induction heated, quenched, tempered and then ground to correct diameter in one continuous process, on one machine that does all those steps in a very short space of time. On a turbocharger, only two parts of the spindle get hardened, which are the bearing areas at either end. I also doubt that the bearing areas are hardened all the way through, the hardening is probably mainly in the surface, and does not extend through the entire thickness of the turbocharger spindle.
@emac1ennan the way to do this is by removing the pedal body, and then using a stud removal tool on the pedal spindle. It is a camming action, so it grips tighter and tighter on the pedal spindle the more force you apply. I hope you are not planning on reusing the pedals!
