FYI: I've been posting on the official Kodi forum and while this is a years-old know bug they offer an easy workaround for the subtitle issue: track #2 won't be displayed until you do a seek back or forth once. I can live with that till it eventually gets fixed.

There are, actually, LE13 versions that supports internal and external subtitles for the C2 (https://test.libreelec.tv/13.0/Amlogic/odroid-c2/). The latest version that worked for me is the 20240710 nightly.

So LibreELEC-AMLGX.aarch64-13.0-nightly-20240715-a8655f2-odroid-c2.img.gz doesn't work for you?
My understanding is it would have broke on July 18th due to the mesa bump, but the nightly builds had stopped during that time.

Subtitles are broken on Amlogic devices that use a Mali Utgard GPU (all GXBB, GXL and GXM boards) due to changes in OpenGLES shaders that Kodi uses. The developer who made the breaking shader changes (Sarbes) is aware of the issue caused, but he doesn't appear to be doing anything about un-breaking things either.
I assume Allwinner/Rockchip devices are also impacted as some of them also use Utgard GPUs, although I've not seen user reports.

That's correct.
