ledger-live VS GlacierProtocol

get Ledger's public key from their git repo. (Assume that hackers cannot modify it.)

Ledger Live is Open Source - you can always see the latest details on github https://github.com/LedgerHQ/ledger-live/blob/develop/apps/ledger-live-desktop/RELEASE_NOTES.md

There is no Ledger device API that Casa could call to export your seed phrase into our possession. You can verify this for yourself by checking Ledger's documentation here: https://github.com/LedgerHQ/ledger-live/tree/develop/libs/ledgerjs/packages/hw-app-btc

I just wasted a few hours of my life scanning the Ledger Live code base. And sure yeah it's open source and clonable as you can see here https://github.com/LedgerHQ/ledger-live it's also pretty much updated as the last merge to develop is 19 hours ago. So first off the firmware is proprietary meaning not open source and normal people won't have access to it. So there's no freaking way to confirm nor debunk what the comment OP see IN A TREZOR SUB unless you can hack into the Ledger device memory one way or another but that requires hardware and firmware knowledge that I don't have nor a majority of software developer.

Secure keys with glacier protocol.

Here are the things people with more than a little bit of money do: https://glacierprotocol.org/

Alternatively, you could take the probabilistic approach and assume that x number of hardware manufacturers are not in on a ploy to steal your money, which is the approach detailed in the Glacier protocol security guide: https://glacierprotocol.org/

At this moment, most "non- reliant on a 3rd party" and secure way to do this is the Glacier Protocol (https://glacierprotocol.org) - but it is extremely complicated for most users and impractical for not large amounts of money (less than $100,000 equivalent)

And here's a very verbose security guide to help you think about when you might want to use some of these things. https://glacierprotocol.org/
