At this point I'm going to grab a cold chisel and try to spin it per your suggestion Andrew. Can't hurt to try! If I can't spin it, then I'll try and shear it off and hope I can get some pliers in there to spin the screw shaft more easily than my attempts to do the same with what remains of this bolt.

It will take a while but not high effort. If you can't get it to turn you can simply spend 20 minutes slowly chiseling the head completely off.
I suspect you have some galvanic corrosion that's welded the bolt in and you can't get any useful penetrant in there.
If you have a straight shot to the bolt and can use a big extension (1/2" a must) you can use a hammer impact screwdriver with your rounded bolt sockets.
If the socket won't bite with hammer Impact, then next thing I'd try (before chisel the head off) is to make a slot in the head and turn into a flat blade screw.
You can use a chisel or a Sawzall blade (manually with tape wrapped around to make a handle)
You said Dremel won't fit but what about with a right angle adapter?
The fact that the bolt head shows so much wear means the war is already won. You can absolutely cut the head off one way or another so it's only won battles you will surely win the war.
I'm thinking once the part is off you will have a lot more space to work.
Use a file to cut six faces on the bolt shoulder and turn it into a smaller head you can pound a normal 1/4" drive socket. Then with penetrant you turn in first to help work in the penetrant. And like a stuck tap you work left and right more and more until it's free.
