I wish I'd have known about this in advance but Nismo and Radio Le Mans have teamed up for a broadcast in English! It's live now. It's also an experiment "Please note: THIS IS A TEST - it could last the full race, it could last 2 minutes (hopefully the full race...) but please join us in this exciting experiment!"

The 'experimental' feed is imperfect. On the plus side, whenever it hangs up it seems to restart where it hung rather than skipping. The Radio Le Mans guys appear to be learning about Super GT as they go but that's actually a bit of extra entertainment IMO.
