Generally speaking it's total carbs, although you are correct to query the polyols. Most find polyols don't trouble their bloods, but like most things with this frustrating condition, so do!
One general point I'd make is, please also be a bit mindful of poertion size when assessing whether something is suitable or not. By that I mean, if something is say, 8gr carb per 100gr, but a portion is 300gr, then that'll be 24gr carb per portion. If something is 30gr carb, per 100gr, but a portion is a teaspoonful, then that's not going to be a big hit, carb-wise, and may improve the enjoyment of the meal.
OK, that probably feels like a bit of fine tuning at this point, but just worth bearing in mind.
Good luck with it all!
