I'm thinking bead not seated properly as well. Also tire levers aren't going to damage your tubeless tires. You should be able to reference a seam on the sidewall just above the rim. If the spacing is not uniform all the way around, it's a bead seating problem. If you do not have a seam you can reference, I would ride them a little bit to get some weight on there and see if it doesn't pop into place. Barring that, remove the tire, put some straight liquid dish soap on your fingers and run it around the bead and reinstall, air it up and putt a little extra psi in and it should pop into place.
