I have had success in the past randomizing things that weren't intended to be random using a script. Keep all of your startup videos in one folder. Set Kodi to use a generic named video (IE introvid.avi) in a location NOT in your folder of startup videos. Write a script or bat file to choose a random video from the startup video folder and copy (overwrite) the introvid.avi with the random file. You would then have the script or bat file launch Kodi.
