i would echo stephanie and antonia about the filling being sweet enough! however, if you're really concerned about how sweet the pie dough is, you could try rolling it out in something sweet, like cookie crumbs: https://food52.com/blog/18412-forget-flour-roll-out-your-pie-dough-in-cookie-crumbs

Many pie crust recipes don't call for sugar. You'll be fine - in fact it probably will be better without the sugar, when used for a pecan pie, (I've been making pecan pies for my sweetheart for over 35 years and I can't remember ever using a crust with sugar. ) Happy Thanksgiving! ;o)

If you have time, start again and freeze the sugar-free batch in the freezer for a future project or experiment.

I assume this is for a pie you are serving to Thanksgiving dinner guests.

It should be fine. The filling is probably sweet enough. It will taste delicious.
