I see it. That sucks and i know how hard it sucks because the same thing happened to me installing rotor bolts in my CZ rim. I got it out by using a steel scribing tool with the point placed against an edge in the portion left in the hole. I used a hammer to tap the bolt counter clockwise. It was a lengthy process. You are in luck because the threaded portion is close to the top of the hole. Looks like there is no sharp edge to catch the point but you could try that small divot at 6 o'clock. Careful not to jab the threads in the engine case.
If that does not work, go to hardware store and try a small reverse drill bit. Tap a center punch and sometimes the bolt will spin out when the bit catches. Maybe it would be best to first drill a shallow hole to insert the reverse bit. That would keep the reverse bit from walking which it is sure to do
Or go to hardware store again and get an easy out. Probably the best way to do it if you're gonna drill anyway. The only thing that could go wrong is if you don't drill the pilot hole off center and chew up the threads in the case. Then you try a thread cleaner tap. If the threads are damaged and loose from fixing, I'm sure blue loktite would kepp the screw in. Or if you want to go all out on damaged threads, redrill and retap and go to next bigger screw.
.....or just leave the chain guard off. I did. All it does is catch flung grease.. Maybe it would prevent the chain from wrapping around the engine sprocket if it fell off the rear sprocket.
If you don't want to do it, a good mech could probably get it out for $50. Might be better to leave it fresh if this looks like it is going to be a real tough job. You don't want to futz it up for the mech by drilling off center or marring up the smooth break where they need to drill. Then it will become a big job for them.
Sorry you had this misfortune. I know what a pain it is. You'll get it out. Consider that the shop probably would have just put the chain guard back on without the bolt. or maybe not put the chain guard on and threw it in the trash.
