What do you do with those cheap prehung doors with hinges that are morticed to the point where the door is basically touching the jamb, leaving a 1/4″ (or bigger) gap on the other edge? I’ve tried bending the hinges with vice grips, and most of those jambs won’t take being dissassembled very well. So. What do you do about it?

Unless the jamb is sized wrong for the door, it can only be that the mortices are too deep. That can be solved by shimming the hinges in the mortices. I rip 2x scrap to thickness required and shim door and/or jamb as required.
Can you replace them with heavier duty hinges the same size? If you have those real thin hinges I often see on prehung hollow core doors, you can probably get heavier, thicker, hinges which shoud help. If you shim them, I'd use thin strips of plywood, I think they stand up better than real thin slices of wood.
I guess you already considered planing the hinge side of the jamb to get that reveal, then cutting 1/8" off the length of the top jamb.
Most of our area suppliers get their doors from their same distributors. Many of these distributors have a door shop where the pcs are prep'd and assembled. If they get in the wrong mood, poor reveals can happen anywhere (everywhere). Poor set up and a 5 dol/hr assembler produce hundreds of prehungs that are wrong. Builders that buy enough doors have some clout with their complaint. Us remodelers by too few at a time to warrant any real listening by a rep. The last house I trimmed out didn't have one door that was right outta the box. My complaints did put the icing on the cake in them dropping that distributor. When prehungs start costing more in changes than on site or builder prepped door units you're tempted to charge the customer for hanging and preping their doors so they end up with a quality finished product. Prehungs are certainly one item that they've lowered production standards on to keep the prices low low low. You wonder how they can sell a prehung birch HC for 40 bucks and they're happy to deliver the answer. If they make the stops any thinner, these doors will swing right through the openings.

Well, maybe this just seems like a great place to go simple, Once the door is hung loosen the center hinge on the jamb side (with the door in the open position)insert a piece of cardboard cut from the box that hinges come in(not corrugated cardboard)cut to the proper size for the hinge your working with, usually 3 1/2 x 3 1/2 or 3 x 3.
Install 2 thicknesses to start and add/remove from there to suit. I keep several of these shims cut to various sizes so they're ready to go when I need them. Continue this shimming on the other 2 hinges.
