I was hoping to make stew, but I made soup by forgetting to add thickener–my intended thickener was keto flour because, due to an autoimmune disease, I cannot have wheat or corn or potatoes.
I was just looking up how to turn soup into stew and found a recommendation of mixing flour with cold water, and adding that mixture to the soup.
Is there a way to thicken soup without use of flour?

I wouldn't actually call a soup with thickened liquid "a stew", for me a stew is a cooked dish with very little liquid altogether, be it thick or thin.
Because of this, I would suggest a very simple solution: pass your soup through a colander, catching the liquid. Then return as much liquid as you like to your vegetables, to get your stew. Keep the rest of the liquid to use as stock for another dish, or to drink pure as broth (you may have to freeze it if you don't plan to cook with it soon).
The second workable solution is to add more vegetables, grains or noodles and cook it more, as one of Juhasz's suggestions, but it has two drawbacks. First, it contradicts your keto restriction, and second, you will likely overcook the original vegetables, if you used sensitive ones.
All other solutions, including the starch, will produce a thickened liquid, but not actually a stew-like dish.
