I just checked, 11-6-3-14 connecting at SAC, GBB, and LAX consists entirely of guaranteed connections. If booked on a single reservation using Multi-City or an agent the entire trip would be guaranteed. Whether or not it is a good idea is a different issue, but there are no connections lacking the guarantee on that itinerary.
While agents have the capability of booking connections that are not guaranteed, they normally will not. They might do it if pressed and warning that a given connection isn't guaranteed, but they won't do it on their own initiative.
PS, I verified the 6-3 connection at GBB with a phantom OMA-KCY booking. That routing comes up, so that connection is guaranteed.
