As far as plants go and I would guess seeds along with it, it's from the Apiaceae family which is the same as carrots and parsley, so the plant itself is very paleo. The seeds probably have less anti nutrients than most other plant seeds.
Good question and wish I could help more. I don't eat celery seed and didn't know it was used for anything. If you are just using for flavoring I'd guess you are fine. If using to make a flour, then it might suffer from some of the same issues as grain flours to a lesser extent though I'm not sure.
