If you don't mind paying ~2$ a month, you can get Family Premium using a VPN (I used India)
Current working method from HUKD:
(Private/Incognito browser is best)
Create a new Google Account.
Enter card details.
Enter a fake billing address, any random address generator will do, as long as it’s from the correct region.
Then select Try it Free.
Navigate to YouTube, press YouTube Premium, and double-check that everything is in the right currency.
Enter the same credit card and address information you used for creating the new Google Account.
Click Buy 👍
You can then add your main Google account as a family member.👍
I believe any accounts joining the family need to first have a Google Payments profile in the country the owner of the plan is in before you can join. Or is that not the case anymore?
And then I might eventually get banned for abusing/bypassing regional pricing 🤷♂️. It's a nice workaround but that's all it is, it's gonna get worse with yt
