Yes, you can lose your Bitcoin if you are too hasty in responding, this is definitely not only happening to Trezor as a cold wallet, other cold wallets must also get the same attack and try to trick all of us who have it.

Why do you call Trezor a "cold wallet"?

Any wallet that you connect online via cable or wirelessly does not belong to that category and people are just fooling themselves into thinking that their coins are absolutely safe when that is not the case. Besides, the case you describe can happen to any type of crypto wallet, all it takes is that you are naive enough to believe that you need to enter your seed where they tell you to.

I think Trezor can be used as a cold storage since it is possible to sign a transaction offline with it and broadcast separately to the bitcoin network. You can go ahead and create an unsigned transaction with electrum wallet, the unsigned transaction would be saved a PSBT (Partially Signed Bitcoin Transaction). Then you can go ahead connect Trezor to a computer and use the wallet software to sign the transaction inside the device(without the keys leaving it) without the internet.

After that you can send it to the network using online broadcasters like Electrum, mempool.space, e.t.c

Here is more info I found upon my research on how to sign it.

Send tab -> fill info -> click send - make sure all is fine here, click sign - confirm on trezor - click save instead of broadcast. Save the file to pendrive or something
