what makes you think they aren't dead
Because I ran a triple breakout board IMU with your same sensors without LLC and with pullups enabled for about 5 months.. that was when I still was learning stuff.. about one year ago.. those three sensors still works perfectly. I'd say that you may shorten their life but a couple tests with the pullups on doesn't fry them.
What board are you using? Can you post a picture of your connections?
