Hello @EclecticShoppe thanks for your post, and welcome to the Square Seller Community! We're glad you're here!
You can temporarily turn off online ordering from your Square Dashboard. Go to ONLINE, and you should see an option to turn off ordering. This will still allow in-person and POS sales, just not online web ordering. If you want to delete your items all together, you can edit your items from the Dashboard also. You'd select those items and then "delete".
