Preheat the oven to 350°F (175°C).
In a skillet, heat olive oil over medium heat. Add the shredded chicken and sauté for 2-3 minutes.
In a mixing bowl, combine the sour cream, cream cheese, green salsa, garlic powder, onion powder, cumin, salt, and black pepper until smooth.
Add 1 ½ cups of shredded cheese to the sauce mixture, reserving the remaining cheese for topping.
Take a low-carb tortilla and fill it with about ¼ cup of the chicken mixture. Roll it up tightly and place it seam-side down in the baking dish. Repeat for all tortillas.
Pour the remaining sauce over the rolled enchiladas, ensuring they are well covered.
Sprinkle the reserved shredded cheese on top of the enchiladas.
Bake in the preheated oven for 25 minutes or until the cheese is melted and bubbly.
Remove from the oven, let cool for a few minutes, and serve warm.
