In a bowl, mix the buttermilk, pickle juice, and 1/4 of the seasoning blend. Add the chicken, cover, and refrigerate for at least 2 hours or overnight.
In another small bowl, mix the mayonnaise, fresh dill, lemon juice, Dijon mustard, salt, and pepper. Set aside.
Preheat oil to 350°F.
In a separate bowl, mix the flour with 1/4 of the seasoning blend. Dredge chicken in the flour mixture, pressing firmly to coat.
Place coated chicken on a baking rack while oil finishes heating.
Fry chicken for 5-6 minutes, until golden brown and reach an internal temperature of 165°F.
In a separate bowl, mix some of the hot frying oil (about ¾ cup) with the remaining seasoning blend to create the hot oil. Baste over the fried chicken.
Assemble sliders by spreading dill mayo on the buns, adding lettuce and pickles, then topping with the hot chicken.
Serve immediately and enjoy!
