Considering the following example, would you use the Potassium Sorbate as stated in the instructions or would you leave it out?

RJS Super Tuscan
SG 0.996
Added oak dust to primary and raisins+spiral to secondary
Going to bulk age for at least 6 months
No plans to back sweeten

I would love to exclude as many chems as possible in my wine but I'm wondering what exactly are the chances of refermentation and popped corks?

You don't need it if you've fermented dry and aren't adding any additional sugar.
Leave it out. it serves no purpose if you do not intend on sweetening it.
I voted to use it but the only time I use it is when I back sweeten, which is most of the time.
If there is no plan to add any fermentable sugar source after this must has reached its FG and is eventually ready for bottling there would be no reason to add sorbate. It would be an unnecessary additive.
