Tap it to the next size bolt, drill through and use a nut, epoxy the hole and drill/tap a new stock size one, use a small wisegrip to squeeze together the pump and the block (leaving the pliers permanently in place), JB Weld the pump to the block or use RTV to seal the pump to the block AND leave the vent valve permanently open on the overflow tank. That's about all I can think of right now.

You may know this, but there are several different length bolts on the water pump. If you put one that is longer in a hole that should only have a short bolt, it bottoms out and you keep on cranking, it could strip out the aluminum threads on the casting.
Chasing threads is usually done with a tap.

They typically don't have a taper, they are more like a bolt with slots in it.
I have used a Dremel to put a couple slots in a hardened bolt to "chase"
the threads clear prior to torquing.

That's why I said "usually". I've done the same with modified bolts or a bottoming tap for blind holes. Listing out every possible option to someone who doesn't know what chasing threads is overkill, IMO. YMMV.

I just felt like leaving the end of the answer to posterity.. I'm always surprised how many people don't know about thread chasers, broke tap extractors, and uing left hand twist bits to remove broken bolts and screws..
