you can buy bitcoin KYC free on bisq.network (but there is a premium). Very low risk of loss of funds. You can even use zelle which is supported by most banks.
Bitcoin ATMs definitely have surveillance cameras - if they don't, the area surrounding their location do. As far as I know there are only a handful of older Bitcoin ATM brands that don't have a camera and even the brand I'm thinking of Lamassu has added cameras in their later models.[1]
From there, send your coins through a samouari whirlpool https://samouraiwallet.com/whirlpool
Then send them wherever you like.
There is still some counterparty risk (what if you're buying coins from the CIA, or whatever), but it's almost minimal.
Buying coins from a Bitcoin ATM is even easier, if there's one near you.
