The custom route injection for this is kind of hideous:

nginx:
  config:
    serverSnippet:
      location ~ /ruler/rule_groups {
          proxy_pass      http://{{ template "cortex.fullname" . }}-ruler.{{ printf "%s.svc.%s:%d" .Release.Namespace .Values.clusterDomain (.Values.config.server.http_listen_port | int) }}$request_uri;
      }

Or is there a way to call that $rootDomain function the other routes use from the values file?

I don't know, have you tried setting $rootDomain? I assume the context might be different
