Technically multi-signature wallets can create Lightning channels too (correct me if I am wrong guys), but the feature is not available in the wallets we use for example in Electrum.
To the best of my knowledge, it's not part of the Lightning BOLT / specification: https://github.com/search?q=repo%3Alightning%2Fbolts+multisig&type=code

Although you can certainly build a client that is capable of doing so. The challenge will be that you'll need access to all signers' keys at all times in order to update channels in a timely manner.

The feature is available in some wallets like Muun Wallet which is 2 of 2 multi sig wallet.
What they're doing is having an online service which auto co-signs. If it goes offline, you'll have issues with your channels not updating.

The main question to ask yourself is: if your keys are on an online machine anyway (required for Lightning), does using 2 or 3 keys instead of 1 increase your security? What attacker model do you need to make this statement true?
