Lentils are (in my book) high carb. Maybe not quite so high as potatoes, but I don't eat either these days. I don't pay any attention to GI, as it doesn't seem to have any impact on me. You'd have to try them and see what they do to your BG over a few hours.
TBH I'd go for ah honest packet of crisps . Anything so processed is unlikely to be low GI.
Once a week I have some veg crisps but that's because I prefer them to Pringles and not because I am deluding myself that they are any better.
If you enjoy them eat them or limit yourself to a few Pringles unless 'once you pop you can't stop' etc.
