I have an aluminum oil filter adapter that has a 10mm steel banjo bolt for the turbo oil feed line. The last one I stripped due to poor fit of the original line and the filter adapter had to be replaced. So with two new copper washers and around 120 lb" it was still weeping. How tight can I go?
Torque spec for banjo bolt

On BMW where there is no torque listed I take banjo bolts to snug and a ¼.

The front caliper banjo bolt on my Jeep specs 18 ft. lbs. 120+ ft. lbs. seems very high, unless I misunderstand your application. A general Google search shows a torque of 12 to 30 ft. lbs. +/-.

One of (the harder of) these surfaces should have a phonographic finish (series of rings), also.

Is the bolt 10mm across the wrench flats or is the threaded diameter 10mm ?
Makes a big difference in torque specs between the two.

I just did a Camero, the hose banjo bolt spec is 41 ft lb in the aluminum caliper. Most cars are between 15-40 ft lb, I would try 15 ft.lb first go up in 5lb increments but I probably wouldn't go more than 30 ft.lb.
treat it like you would a drain plug.
That looks like it may have had a thread repair done already? try aluminum crush washers. This is just an example of 10MM check you i.d and o.d. aluminum washers take less torque to seal than copper. tighten it a little more than snug like 144 in.lb

What caused the initial stripping out was due to the replacement oil line from ATP which was marketed for the Genesis Coupe 2L turbo had too thick of a banjo and the oil line was an inch too short. So after a couple R&Rs it stripped out. Here is the OE bolt and the ATP banjo.
I got a bolt from a Dodge application that was a couple mm longer.
ATP did send a new line 1 inch longer and with a slimmer banjo for no charge.
I tightened it up to 150 lb in yesterday and it was still leaking. So I cranked it a bit more today. If it's still leaking then I guess some aluminum washers are what I need.

Yes that bolt is very short on threads, 4 threads isn't nearly enough. If its a 10mm bolt you need a minimum of 15mm threads or 1.5x the bolt O.D. I would try aluminum washers.
