If it passed the autoland self test at 1500 and had no message regarding it prior to the 100 RA, I actually doubt the NO AUTOLAND can display below 100 RA.
My somewhat simplified system manual does not show a NO ROLLOUT message. I don't think that while it is only in armed mode (above 5 RA ) that ROLLOUT can display with an amber line though it, indicating degraded function. So it would have to change from armed to active at/below 5 ft to then show you degradation. We train in the sim that the PM will give a "no rollout" callout and then a "steer left/steer right" call using the LOC for centerline if ROLLOUT does not become active or is degraded with a line through it. But not to go-around as you will most likely be the TO/GA dead zone by the time that you realize the failure and try and do anything about it.
