You don't need LCC although there is a CF from Rodenstock to help with the vignetting which is clearly evident in the sample pics here.
Given that you don't shift at all, distortion and light falloff correction in C1 can easily take care of the file. Since it is fully integrated, the files will contain metadata regarding the lens and apertures which will help C1 to pull up the right lens correction data directly without further need to select the profile from the user.
There's maybe 2-3mm shift. I have one in XT23. Its a great lens for landscape, but really wide so tricky in use.
