I just wrote an ansible role to install and configure LNbits with just a single command. It hasn't been through code review yet, but it worked on my test environment.

You can use the nginx.nginx, geerlingguy.certbot, and nginx.nginx_config roles to get TLS certs from LetsEncrypt. I've tested that as well.
