Thanks for catching this Ulrike. The lltxmath prefix indicates this is from Philipp’s lualatex-math package, which I don’t have much to do with at the moment. (It is basically a spin-off from unicode-math after he realised how much legacy code needed patching.)

I assume Philipp is on this list and can reply further :)
