Default Help Needed w/ Leaking Brake Line Fittings from SS Line Install

So I got a set of used Z1 Premium SS Brake Lines from a user and ready for the install.

As I was removing the old SS Tubes from the stock Line block, the hex fitting ceased up and the Box wrench slipped and rounded the hex leaving me unable to loosen up the fitting.

So I ended up using Vice grips (which was a stupid idea even though it got the job done of loosing up the hex fitting), I completely destroyed/mangled the fitting and now the hex fitting is leaking - I think I might have deformed the fitting. And it left a fat leak as I tried bleeding the brake using a power bleeder at 15 psi.



To temporary fix that particular fitting using some PTFE pipe tape wrap, but I'm still getting small leaks in the front Driver side:


I know I'm not supposed to fasten the crap out of these fittings as they are meant push up against the flared flange of the tube. I have ordered some new brake tube (where there fittings are destroyed):
46245-JK60B
46246-JK60B
46315-JL00A
46316-JA00A

In the meantime, I don't see any leak at 15 psi except small drips from Front Driver side. By the time I got done with bleeding the brake system, putting it down back on the ground, I depressed the brake many times and it's totally soft and went straight to the ground. I started the car, did the same thing, but still not really any leak I can find.

Any advise what's going on? Possibly a lot of air in the line? Should I be using these tools? What's the torque value? How do I torque these fittings? I'm scared as heck now to work on brake lines. I used to do all my brakes but this is the first time I had this much issues.

These are the tools I used:
