Thanks for your answers. Yes, i'm aware that it is recommended to generate the seed phrase offline.
My feeling is that hardware wallets are convenient and safe to use but i'm not comfortable to let them
generate the seed, according this:
Devices such as Trezor, Ledger, ELLIPAL and most wallets come pre-loaded with private keys, meaning a level of trust is involved. Private keys on the BC Vault are user-generated for ultimate anonymity.

Personally i use an electrum wallet, but generated the seed with the Python module "secrets" installed and use
a live USB in Airplane mode. Indeed, electrum does not generate BIP39 seeds natively.
