Preheat your grill to medium-high heat, approximately 400 degrees F.
Pat the chicken wings thoroughly dry with paper towels to ensure a crispy skin.
In a large bowl, toss the wings with avocado oil, smoked paprika, garlic powder, onion powder, sea salt, and black pepper until evenly coated.
Place the wings on the grill grates and cook for 15-20 minutes, flipping halfway through, until the internal temperature reaches 165 degrees F and the skin is charred.
While the wings grill, whisk together the Greek yogurt, lemon juice, and dried dill in a small bowl to create the zesty ranch dip.
Slice the celery sticks into 3-inch pieces for dipping.
Serve the hot, smoky wings immediately with the chilled ranch dip and crunchy celery sticks on the side.
