the bolts holding my starter motor on have broken off unfortunately. without checking for clearance on my drill I bought an extractor kit. after looking at videos I realized that this has to be done very precisely making sure to drill in the center of the bolt at a right angle. unfortunately, my drill will not allow for that. Is there any other solution for this?

A steel bolt can be dissolved with a saturated mix of alum and water if it has been broken off in aluminum. That is how they get broken taps out of aluminum at machine shops where a tap is so hard you can't drill it out. If you damage the aluminum around the bolt its either a new case or new motor.

I borrowed a dremel from my friend. He told me that it is possible to drill a notch in the bolt and sometimes you can unscrew it with a straight screwdriver. has anyone ever tried this?

Yes, but there has to be room to fit the screw driver in there.

should I try using the bolt extractor with my dremel if I can get it to fit?

You could grind a center spot with the dremel first so that the extractor is centered. You do need to be centered and be drilling straight in to the bolt. It will not work if you come into the bolt at a angle. either an extension or pull the motor if you can not get a straight in shot with the drill and extractor.
