It could be, but I could also see it just as easily being a foreign language that is readily identifiable to broad swathes of Western society as a language, rather than pure gibberish, yet also has relatively few people left who understand it. You don't run the risk of native speakers either saying "That's ridiculous, he's just reading a gazpacho recipe, not summoning a demon," or complaining about their language being demonized in media.

Plus, Latin has long been associated with the Catholic church and its ancillary organizations, and academia, which have long been soft targets in many anglophone countries.
