Preheat your oven to 350°F (175°C).
In a large mixing bowl, combine the cooked shredded chicken, cream cheese, sour cream, half of the cheddar cheese, half of the mozzarella cheese, garlic powder, onion powder, cumin, and salt and pepper to taste. Mix until well combined.
Warm the low carb tortillas in a skillet for a few seconds on each side to make them pliable.
Spoon an equal amount of the chicken mixture onto each tortilla, roll them tightly, and place them seam-side down in a greased baking dish.
In a separate bowl, whisk together the chicken broth with the remaining cheddar and mozzarella cheese until smooth. Pour this sauce over the rolled enchiladas in the baking dish.
Bake in the preheated oven for 25-30 minutes, or until the cheese is bubbly and golden.
Remove from the oven, garnish with chopped fresh cilantro, and let cool for a few minutes before serving.
