EDIT: I was trying to rerecord the video so it's under 10MB so I can attach it. It turns out it's not the llamas breaking the item frame after all in my case! The item frame is right above a gate. You can only place the item frame when the gate is opened. When you close it, a few seconds pass and it breaks the frame.
------- Hi! I ran into this as well, and I wondered if it was a bug or a feature. Then found this JIRA issue. I am not sure if the mobs can grief setting is on or off in my case, I have a vanilla Realm, settings untouched. In addition to the original poster's problem, after the llama breaks the item frame, you cannot place it back on the exact same location. I am trying to do it frantically on the video. Almost as if the item frame was still there. But if you target it with F3 open, the targeted block is indeed what it should be, terracotta in my case. They seem to only break frames and frames that are placed on the same height as their head, I assume it's intended.
