Place the chicken drumettes in a large bowl and drizzle with the olive oil; toss with tongs or your hands until evenly coated.
Sprinkle garlic powder, Italian seasoning, onion powder, black pepper, smoked paprika, cayenne, and kosher salt over the chicken; toss again until the drumettes are fully seasoned.
Preheat the air fryer to 400°F (200°C) for 5 minutes.
Arrange the wings in a single layer in the air fryer basket without overcrowding; cook at 400°F for 20 minutes, flipping the wings halfway through. Work in batches if needed.
Remove the wings when crisp and cooked through; serve hot.
