Try rotki

Pretty sure https://rotki.com folks would add it soon.

If you’re keen, I’m trying / learning to contribute to a Python project: https://github.com/rotki/rotki I’ve been in dad duties for the past 10~ish years so there’re a lot to catch up on.

Check out Rotki. It's open source, keeps data local, and it comes with a bunch of features for free. Not everything is integrated yet as it is still under active development, but it's the best portfolio tracker out there that I know of. And it's only $12/mo for the paid features, which goes to supporting the indie dev team lead by Ethereum OG Lefteris Karapetsas.

I am talking about using diceware or Seedsigner's implementation which can even be verified independently.

Much easier, you don't have to try so many words, maximum 16 words. It's described here: https://github.com/taelfrinn/Bip39-diceware

I think it's best to create your own seed phrase, but the last word has to meet the checksum requirements ane I couldn't get it to work. Here is a tutorial but it didn't work for me - I might try again if I have the time: https://github.com/taelfrinn/Bip39-diceware

If there's concern about the RNG, you can [manually generate a key using dice](https://github.com/taelfrinn/Bip39-diceware). Real randomness! Call me paranoid, but IMO it's worth the extra 30 minutes or whatever. One less thing to trust.
