+2Single vs double opt-in
With a list
When subscribing a profile via API with a list, the list's opt-in process determines the opt-in process used to subscribe the profile for that API call. The account's default opt-in settings will have no impact on the behavior here when a list is a provided.
What is a List? We are not using List API. Every time a customer is added in our POS, we will confirm the subscription and use Subscribe API. What has this got to do with list?

When you subscribe a Profile to marketing via the API, you can choose to subscribe them to a specific List, which is a static group of profiles that you can use to organize your marketing communications. Klaviyo recommends having one main list per channel:
If you don’t include a specific list in the API call, that means you are updating the profile’s general marketing consent, without adding them to a List:
Each List can have their own double opt-in settings, that override the account-level settings. So, if you’re subscribing them without adding them to a List, the opt-in process will be decided by your account-level opt-in settings.
Hope this helps!
