My first thought was wheel puller with a very small flat file [jewelers type] worked around the edges first.

Continuing to do this will eventually loosen the bolt.This IS a thru bolt not something that is threaded. certainly one can drill it out using the step approach 1/8 " then 3/16 then 1/4 till you get to 5/16. Gently tapping or drilling you should find this removal easier then you thought.

Then you've got a real mess of hardened tool steel. I would first drill several small 1/8" holes in the lead around the circumference of the bolt. Then, I think tapping or pressing it out is the way. The wheel puller would probably work. You'll end up with an enlarged hole that you can either use a bigger bolt, or washers to deal with. I agree some of the hardware that comes with cheaper L 16s, is inferior. I've had plenty of those square heads come off with minimal torque.

Both sides snapped off flush with the flag. I was thinking try to drill it out or maybe a small gear pulling tool? I will never again use the non stainless hardware supplied by the manufacturer... Picture attached for reference.
