Even if you say you want a filter it's good to keep in mind that in different cultures specific swear words or swearing in general can be considered much less or not offensive at all. I know this is the case here in the Netherlands and considering Larian is located in Belgium they probably have different sensibilities about swearing then someone in the USA might have.
I doubt Larian will do this as it's a feature that could potentially take either a lot of disk space or a lot of time to create.
