How do you turn it off for brew cask?

Anyway this option should have been available in their man page. But anyway they have clearly mentioned it.

If they want data, I will happily fill up their survey form but please don't take it for granted that my personal data is yours otherwise I may go to China for their great wall.

Any idea what to block if I want to just completely block google analytics at the firewall level?

/etc/hosts should do it, I suppose?

The way I accomplish this is by setting up an dnsmasq DNS forwarder service. Find domains list for ad blocking / privacy on the internet and add these entries in dnsmasq's config.

The entries look like this:

address=/doubleclick.net/0.0.0.0

address=/gravity.com/0.0.0.0

address=/outbrain.com/0.0.0.0

...

Then set up the router's DHCP to use this server.

Little Snitch is excellent for this. I remember running brew at some point and being asked by Little Snitch if it could connect to Google. I said "deny forever" and have never worried about it since.
