Let's Encrypt isn't the only free ACME provider, you can take your pick from them, ZeroSSL, SSL.com, Google and Actalis, or several of them for redundancy. If you use Caddy that's even the default behavior - it tries ZeroSSL first and automatically falls back to Let's Encrypt if that fails for whatever reason.
