I had the end cap crack on a 2" irrigation line buried 1-2' underground. It sprayed downwards, clearing away 2' of dirt vertically (3-4' total downward now). I found an area about 3-4' away from this site that also had water rushing up from it, so there is at least a 3-4' deep horizontal hole as well, all within feet of my patio and pool pump cement block.
How do I fix this?
I live in Tampa, FL. Ground is kinda of a dry clay/sand kind of dirt.
Right now, my idea is to carefully dig up where I think the hole is so that there's no cavity down there. Flush the broken line. Re-PVC-glue it was a new end cap. Refill hole it with some clay/compact dirt filler.

I think your suggestion/idea is the solution. Unfortunately, when it comes to filling in earthen holes with earth, it's a very simple operation involving digging tools and excess clean fill.
Personally would excavate around and fix the broken end cap, and backfill. It's no more complicated than that.
TL:DR = Grab a shovel and order some dirt.
