LocalBitcoins requires government ID KYC since around 2019 (same as Paxful). Western Union generally requires ID (for sender and recipient), even if you choose the "password" option.

HodlHodl.com, LocalCryptos.com, Agoradesk.com and Bisq.network are KYC-free. You can use cash by mail (KYC-free for any amount) or money orders (for buyers, KYC-free up to $3k). More info here: https://x21.tools/no-kyc
