Preheat your air fryer to 375°F (190°C).
Slice the sweet onion into 1/2-inch thick rings and separate them.
In a medium bowl, whisk together the flour, light beer, egg white, 0.5 tsp smoked paprika, garlic powder, sea salt, and black pepper until a smooth batter forms.
Lightly spray the chicken breast with avocado oil, season with a pinch of salt and pepper, and grill or pan-sear until it reaches an internal temperature of 165°F. Slice into strips.
Dip each onion ring into the beer batter, allowing excess to drip off, and place in a single layer in the air fryer basket.
Lightly spray the onion rings with avocado oil and air fry for 8-10 minutes, flipping halfway through, until golden and crunchy.
While the onion rings cook, prepare the zesty dipping sauce by mixing the Greek yogurt, hot sauce, and the remaining 0.5 tsp of smoked paprika in a small bowl.
Serve the crispy onion rings alongside the grilled chicken strips with the dipping sauce on the side.
