From what I found in UK banks will let 16 year olds to open an account independently.

You could also mail cash (Mullvad), buy a VPN gift card in a physical store or online or get something like a prepaid Visa/Mastercard or a paysafecard.

Even if that is not an option, it's not like age restrictions have prevented everyone underage from alcohol or smoking, people will find a some shady VPN provider or a friend to buy them one.

And also, the transaction can have a very useless business name.
