I just want to clarify for anyone else, the frames in dispute are NOT historical content, they are ads that have been inserted into the video. (I bring this up because taking down historical content for being offensive is not necessarily a good idea, it is important that we accurately remember how thing were, good and bad)
I dont think you'll have much luck reporting the videos for transphobia, just because I dont think google/yt cares about that. But you may have some success reporting them for copyright infringement. They are certainly not official recordings/uploads, and its definitely not free use.
