Can Ledger still extract & transfer my keys/words if I don't use the "Ledger Live" application after the initial configuration?

Hi,

Lets say that I I do this:

- I reset my Ledger Nano so it is like brand new from the factory
- I configure it with a new randomly generated set of 24 words that I will use to transfer all my crypto to.
- I use Ledger Live to upgrade the firmware (if available) and to install the apps for BTC, ETH, etc. At this point, my 24 words maybe have been extracted and transferred by Ledger Live. Who knows?
- I unistall Ledger Live, since I will not use it any time soon (for many months).
- I configure a very long and complex passphrase, which I think could never be extracted and transferred since I won't use Ledger live again anytime son.
- I use instead the MyEtherWallet-com or MyCrypto-com websites (or any other similar website) connecting to my Ledger for ETH, and Electrum connecting to my Ledger for BTC (or any other similar application).

Is there a way for the Ledger device to extract and transfer my keys/words to the Ledger company or to some rogue programmer there that may have coded a back door somehow, if I stop using the Ledger Live application before adding the passphrase?

Actually, maybe I could use the Ledger Live sometimes to update the firmware, but I would have to reset the Ledger device before that so there would not be any keys/words/passphrarse to be transferred. Then I would reconfigure it with the same 24 words. Then, after the firmware update and loading the apps, I would unistall Ledger Live and reconfigure the passphrase. So the Ledger device would have the new firmware and apps, but without having exposed the very long and complex passphrase.

Would this approach work?
