this is the circuit in question, page 3 is the part I'm asking about, not
the PWM circuit on page 1,2:

The IRF4905 and IRFZ44 limit current to 74A and 49A respectively.

The LM324 Quad op-Amp limits Voltage to 32V

What is an op-amp that will work here, but be able to handle 100v or maybe
55v min?

you may have to build your own. 100v signal transistors are fairly common
