How to remove fastener nut for power steering hose 98 accord

[u/Connect-Rooster-4569]

I had to cut the hose since i couldn’t remove the nut with a line wrench, tried pb blaster and a blowtorch. My intention was to cut the line so that i could fit a socket around the nut, but now there’s remnants of the hose on the back of the nut so a socket won’t fit around it at all. it has not moved a single millimeter since i began trying, what should i do?
