Do you have any suggestions on my best course of action? I am uncertain where to ask this as Kodi and LibreElec have areas on these forums and their own.

Anything video or GUI related is pretty much a Kodi issue, it's largely out of the hands of LibreELEC by that point. Maybe there's a startup deadlock or race condition that you're uncovering and seeing first with LibreELEC - do you know if this intro video works reliably on other platforms?

Creating a ticket on trac.kodi.tv is likely your best option in my opinion.
