Add in the chicken thighs, bbq sauce, orange juice, lemon pepper seasoning, brown sugar, and Worcestershire sauce. Give it a stir.
Close the lid and put the valve on sealing position.
Meanwhile, prepare the coleslaw. In a large mixing bowl, whisk together the mayo, lemon juice, vinegar, sugar, salt, and pepper. Add the bag of cabbage and carrots and mix well.
Once the timer goes of on the Instant Pot, quick release the valve to let out steam. Open the lid and remove the chicken to a cutting board. Shred it up and put back into the sauce.
