I think you should be ok there. Don’t make any drastic decisions just yet. I know you’ve expressed that there is a ton of foliage dying, but I would just focus on the dying leaves coming out of buds.. like up top. You don’t want anything dying in your buds, as it will soon turn to rot if left there.
Use trimmers with a sharp tip to snip at the base of the petiole (The stem that connects the fan leaf to the branch) Visual in the bottom of this picture.
Don’t be afraid to separate the nug at this spot to get to it. If you do not cut at the base, you are leaving a small piece of the petiole in there to die & possibly cause rot. It’s better to damage it a little *Worst case scenario* than to lose the cola to botrytis.

The other leaves will die as the plant consumes all nutrition from them & fall off on their . Ridding you of the dead stuff & causing no stress from snipping them.
