Tariffs on goods coming into the US are paid by US residents. (Just had to pay customs to clear a shipment from the UK - I had to pay the tariffs, not the seller.)

That assumes that iOS 15 requires a new phone... which isn't the case. Apple generally has an excellent track record of supporting older devices when they release new major OS versions.
Taking a look at the devices that support iOS 15[0], the oldest one appears to be the iPhone 6S... which was released in 2015. So you could theoretically use the new 1Password 8 on iOS 15 on a phone that is 7 years old. No need to pay for a new phone.
