Combine buttermilk and hot sauce in a bowl and whisk to combine. Add chicken pieces and stir, making sure all pieces are covered. Cover and marinate in the fridge for 1 hour.

In a bowl, combine all-purpose flour, seasoned salt, garlic powder, onion powder, Italian seasoning, and cayenne pepper. Mix thoroughly.

Remove each piece of chicken from the buttermilk mixture and drain off any excess milk. Dip the chicken pieces into the flour mixture, shaking off any excess flour. Place the chicken pieces on a wire rack or plate. Place in the fridge for 15 minutes.

Preheat your air fryer to 360 degrees Fahrenheit.

Place the chicken pieces in a single layer and close the air fryer basket. Air fry for 6 minutes.

In a large, heavy bottom pot, heat 2-3 inches of oil over medium-high heat until the oil reaches 350 degrees Fahrenheit. Add the chicken pieces to the pot, about 4-5 pieces at a time, and fry for 6-8 minutes, until chicken pieces are golden and have reached an internal temperature of 165 degrees Fahrenheit. Remove and set aside on a wire rack to cool.

Add pickle slices and fried chicken on the bottom of each slider bun.

Make the spicy mayo by combining mayonnaise, hot sauce, paprika, garlic powder, and onion powder. Add the mayo on the top of each slider bun. Place the top on the sandwiches. Serve and enjoy.
