And wavelengths (340 - 400 nm) that have strong contributions from solar and Titanian exospheric sources. It's not going to be a significant source of intensity above the "noise".
I also don't know how opaque the Titanian atmosphere is to UV. I'd guess that it's not very.
You should beable to convince yourself with an envelope that it ain't happening.
Maybe Cassini, if in position, could get lucky and catch a snapshot with a UV channel. Mabye....
