Law enforcement can’t just eavesdrop on the conversation without Telegram’s cooperation. The chat contents are still secured by TLS from the user’s device to the Telegram servers.
Smart professional criminals rarely use Telegram for this stuff anyway. There’s WhatsApp and plenty of other popular platforms of end-to-end encrypted

Also Signal has some really shady practices, such as rejecting and killing all third party clients.
