Preheat air fryer to 375°. In a shallow bowl, mix flour, seasoned salt and pepper. In a second shallow bowl, whisk egg and milk until blended. In a third bowl, mix bread crumbs and paprika.
Pound pork cutlets with a meat mallet to 1/4-in. thickness. Dip cutlets in flour mixture to coat both sides; shake off excess. Dip in egg mixture, then in crumb mixture, patting to help coating adhere.
Place pork in a single layer on greased tray in air-fryer basket; spritz with cooking spray. Cook until golden brown, 4-5 minutes. Turn; spritz with cooking spray. Cook until golden brown, 4-5 minutes longer. Remove to a serving plate; keep warm.
Meanwhile, in a small saucepan, whisk flour and broth until smooth. Bring to a boil, stirring constantly; cook and stir 2 minutes or until thickened. Reduce heat to low. Stir in sour cream and dill; heat through (do not boil). Serve with pork.
