Point I am trying to make is if it Connects to the Internet it is a "HOT Wallet" whether it is a "Online Desktop/Web Account Wallet" unless it is a "Cold Wallet" on a Computer with an Electrum Wallet Installed on a Computer not ever used Online etc. etc.
What is a hot wallet, your Leger wallet?
Don't let the terms confuse you. Your ledger device will be connected to the internet but security wise you have nothing to worry about. Your private keys never leave the 'safe spot' on your hardware wallet. Even when you send and sign transactions.
All you have to do is keep your 24 words seed phrase secure and make sure that it isn't saved on your computers or used online in any way.
Even when you use your Ledger together with Electrum you will not be asked to enter your seed.
