Is the threaded part metallic, composite or carbon? Using an alloy insert wouldn’t be difficult, so it’s an odd choice to use threaded tow-based discontinuous composite (aka ‘forged’ carbon fibre) for a threaded safety critical part, but it can be made quite strong. 🤷♂️
Quite a few calipers operate(d) on a similar principle, with duly mashed cables as a result. Not an elegant solution, at least.

I think the kink is due to the concave end of the bolt and that the hole goes all the way through.
File the bolt flat? And have a second bolt going mid way through from the opposite side to plug the hole and act as a base to prevent the kink?

I wouldn't go anywhere near Ciamillo brakes.

@nick_h.
Is this brake caliper design OK? It's a Ciamillo L8 Ultra. My concern is that the cable might come loose. Mr Ciamillo is financially fly-by-night. Maybe he's a good engineer but it's safe to say that he wouldn't have paid for independent testing. Here are the fitting instructions:
The cable goes through the hole then you fix it in place by torquing the cable clamp bolt. The bolt screws into a channel which is just a threaded hole. 
The cable clamp bolt is a tiny grub screw. 
When you torque up the bolt it mashes the cable and bends it into an elbow shape.
Over time, might the 'elbow' in the cable continue to deform...and come loose?
