The shell task at https://gitlab.com/famedly/company/devops/collections/base/-/blob/main/roles/lego/tasks/main.yml#L26 produces a fatal error if the binary does not exist that is ignored, but is irritating.

This should be avoidable by splitting it in two tasks, the first testing if the binary exists and the second (version check) only executed if the first succeeded.
