I’m surprised I had not commented on this thread because I’m pretty sure not long ago someone asked for similar advice.
By Google TV I’m guessing you mean you got a smart TV that runs Android TV?
Because as far as I know, Google doesn’t manufacture televisions, and all smart TVs run Android.
My advice is the same as before:
RULE #1: DO NOT connect your smart TV to the internet. Use a TV box instead.
I understand that using a TV box means spending more money, but that is what I would recommend. I use the NVIDIA Shield TV Pro, which is arguably the best Android TV Box from a UI & UX standpoint. From a privacy standpoint, it’s still Android, but it has less bloatware.
That is an excellent idea, but apply it to the TV box instead.
Don’t connect your TV to the internet and use a VPN to create an anonymous Google account that will be exclusively used for your TV box.
Creating a Google account anonymously can be tricky though because it will require a phone number.
If you live in a country where ID registration is not required when buying or using a prepaid SIM card, (US, UK, Canada(?)), then I suggest you do that as your chances of success are pretty much guaranteed.
If you live in a country where ID registration is required however, which is most countries, then you will need to use a service like SMSPool or JMP.Chat.
I have only used SMSPool, but have heard good things about JMP.Chat too.
Both accept Monero which allows you to pay anonymously.
If you are going to go this route, my advice is the same as before:
