He should be able to get enough heat to bend in increments, sounds like
he has a Bernzomatic hand held MAPP gas torch. Plenty of heat to do
small bends.

Well I can understand why he would grind, a Bernzomatic handheld torch
is okay for light heating jobs, but wouldn't be good enough to do
serious forging. Grinding is a good solution in the circumstances.
We have bail hooks here too, but they have a "T" piece instead of a "D"
for a grip.
Rebar should be thick enough for this application without heat treatment.

An easier approach would be like this :-)
