At this point, there’s only 4 days left of rifle season, but I believe you can use a rifle license to hunt during the holiday antlerless season (you would need to verify this though).I am not a skilled hunter therefore I will use a rifle. Archery equipment is for skilled hunters and in my opinion a true hunt. I would be deer sniping and not hunting.
If going to a physical license retailer is off the table, then you just need to go to the ODWC website and look up licensing. You will have to set up an account, but the process isn’t rocket science.
I wish you the best of luck hunting!
