This is a documented soft dependency: https://github.com/voxpupuli/puppet-letsencrypt#dependencies describes that you are responsible for having the EPEL module present in your environment. Perhaps it can be more explicit in saying that it is a soft dependency and a PR for that is welcome, but this is the desired workflow.
