Preheat oven to 400F. Spray a 9-inch baking dish with nonstick cooking spray and set aside.
In a medium bowl, combine cream cheese, mayonnaise, sour cream, ⅔ of the mozzarella, imitation crab, light green parts of the green onion, garlic, soy sauce, and sriracha. Stir until fully combined, then transfer to greased baking dish and top with remaining mozzarella.
Bake for 25-30 minutes, or until cheese is golden-brown and bubbling.
While the dip bakes, heat oil in a high-sided skillet over medium-high heat. Drop in wonton wrappers and fry for 1-2 minutes, then transfer to a plate lined with paper towel and sprinkle with salt immediately.
Drizzle finished dip with sweet chili sauce and top with dark green parts of the green onion. Serve with wonton chips.
