That IP resolves to rate-limited-proxy-72-14-199-18.google.com - this is
not the Google search crawler, hence why it ignores your robots.txt. No one
seems to know for sure what the rate-limited-proxy IPs are used for. They
could represent random Chrome users using the Google data saving feature,
hence the varying user-agents you will see. Either way, they are probably
best not blocked, as they could represent many end user IPs. Maybe there is
an X-Forwarded-For header you could look at.

The Google search crawler will resolve to an IP like
crawl-66-249-64-213.googlebot.com.
