Nothing seems broken… Needs a preload cap and tightening to spec – then it should be as good as new.
It’s a very common mounting type across many brands of crankset. Once it has been properly preloaded and torqued down, it shouldn’t move! have tens or thousands of miles on 105/GRX cranks like these
Definitely doomed.
However the mechanic might be able to save your crank and reinstall it.
The problem is that I didn’t have a torque wrench with me, and this happened during a ride, so I tightened the pinch bolts using a regular Allen key. However, the pedal came off after about 100 meters, so now I’m worried that I might have damaged the thread inside the left crank arm.

Not doomed, but most shops will want to replace, with the teeth showing wear. It wouldn’t be hard to get it rigged back up, though.
