Threaded bolt snapped off

Heat. Maybe cut a screwdriver slot in it. Do you have someone who can weld a nut to it?

If you don’t have a screw extractor try drilling it out completely. Have had to do that on several occasions.

Bottom pic is where I can get a 1/8" holy started but I probably need a better but. There's no chance I can get any type of threads to catch

You’ll probably have to drill until thin, then pick and tap the rest out.
Drill and easy-out might be ok for something like this too but I’ve never had too much luck there and usually skip that step or hammer in a standard torx bit if the bolt is soft.
Ideally, if you can clamp it all down good, you would take a center punch and work the bolt with progressively-angled strikes.
Center punch is my #1 go-to and I’ve probably retrieved a few hundred damaged screws or bolts on cars and oil tools.

you could try drilling with a left handed drill as well and it might start turning out.

I would have already gone and gotten a replacement pruner

Try to drill it out first, hammer and punch if unable to drill.

drill bit and tap in that size will probably cost more than the pruner itself..

this but the satisfaction of not letting that pruner beat you is pretty good.
