Trezor is the same. Open-source does not matter unless you are actually compiling from source every time and loading that. Every time you update firmware that way, your trezor will be completely wiped too, so you'll have to re-enter the seed

By the way, if you don't trust Ledger's firmware, why would you have trusted their hardware in the first place? And the same can be asked of Trezor's hardware. You have no way of knowing whether the microchips under the hood are following the spec or not. Only trustless way is to build the hardware AND software by yourself, which is doable, Raspberry Pi.

Or to go full paranoid, no hardware wallet. Access your private keys only on an air-gapped linux box to create transaction header sigs. Then take that tx sig and broadcast it from your connected PC.
