What are some tools I can use to convert FLAC files to TrueHD?

ffmpeg is one, though its THD encoder is considered experimental so you have to allow it with -strict -2

Out of interest... What are you creating the Dolby TrueHD stream for?

If it's for creating Blu-ray disc compliant encodes you will need to add/embed a 'lossy' Dolby Digital complimentary stream (sometimes referred to as a 'core').
