Is there a way that I can block incoming and outgoing connections, both LAN and WAN to / from a program in macOS?
(I'm running Yosemite 10.10, but I guess it would be similar across OS versions)

Radio Silence does exactly this — it's an outbound firewall that you can use to blacklist outgoing traffic from particular apps. Little Snitch can also filter inbound as well as outbound connections.
