I think you should try the pacifier a few more times. Baby can smell you and feel the softness of your boobs so they will search for it once they are very near to it. Biting down your nipple sounds painful but you have to bear with it and when they are drifting more deeply asleep, you can try to unlatch itch the pacifier and slotting it in immediately - that s what I did for my Son who was like your girl. Latch. Fall asleep then try to sneak nipple out.
Although this is a passing phase you can consider trying to see what are your child's other soothers, like if baby is ok to hug a toy with your scent to sleep or to suck thumb. Different baby different soothers. Jia you.
