You can delete LODs at a specific coordinate, but trying to delete "all broken ones" won't be possible from SQL.
If I remember correctly for any position that starts with a 6 [6,X,Z] it should be roughly 1/4th the chunk pos.
Otherwise if you have a world where you can consistently re-produce the issue you can upload it as a GitLab issue and I can take a look at it when I have time.
