We supported letsencrypt from the first hour of public beta: https://www.schokokeks.org/
(Fully automated, customers just switch on “Let’s Encrypt” for their host and all magic is done behind the scenes.)
But apart from that: I don’t like such lists. They are incomplete. And they don’t represent details such as if it’s working stable or easy to use. If your desired hoster cares about security does not simply mean if letsencrypt is supported or not. There’s more about that topic.
