Not that I know of. The VNDB page says that the trial version got a Chinese translation, but I have no idea how good it is or if the translators are interested in doing the full game any time soon.
Just a heads up, you might want to prepare to update this soon. It suffers from no-progress bug that is currently under rapid debugging. Scheduled to be fixed on May 1st at 22:00 JST.
It's out, update please. 聖騎士リアナ to v3.5
