Place chicken thighs in a gallon-sized resealable bag. Pour pickle juice over the chicken. Seal bag and refrigerate for 4 hours.
Preheat an outdoor grill for medium-high heat and lightly oil the grate.
Whisk olive oil, seasoned salt, paprika, dill, and pepper together. Remove chicken from pickle juice; discard the juice. Brush all sides of the chicken with the seasoned oil.
Grill chicken for 6 minutes. Flip and grill until no longer pink in the center, about 6 minutes more.
