You may have to snip the line to allow getting onto flair nut with a female easy out. This is a gizmo with left hand twist thread that bites into a mangled nut or such that is used with a socket ratchet.
Something like this.
Than you can make a new line to replace the whole thing**, or splice onto the old line with new fittings and a short length of tubing.
** Replacement may cause more problems when removing the end fitted to radiator...
