Has anyone ever had to turn off an SRS airbag fault tell-tale?

I have an OBD cable and dedicated software for VW/Audi group cars, but I
have also used it in 'generic' mode on the neighbour's Nissan.

You can clear any outstanding 'trouble codes', whether that would put
the warning light out on the dash, who knows, but you'd hope so ...

Resetting things like airbag warnings may not be within the scope of some
aftermarket devices. ODB is generally to do with engine emissions, etc.

Almost certainly the case with aftermarket low cost diagnostics.

Pre-OBD it sometimes required another specific manufacturer plug in
data cartridge that only covered the airbag function and nothing else.

This used the same basic handheld diagnostic device as used for the
engine still plugged into the same vehicle diagnostic socket using a
shared pin on the same vehicle bus with each control unit responding
to a specific poll. .
