"What strategies must a filmmaker use to convince the audience that what they're looking at is an exaggeration, not "reality?" "
Formalistic ones, of course: high saturation images, fisheye lens, any exaggerated imagery is helpful.
You mentioned Gilliam, and I think "Fear and Loathing in Las Vegas" is a perfect example of caricature. FLLV manages to hold that fine line between reality and hallucination through its special effects, bizarre angles, over-the-top dialogue and locations (of course, you really don't have to change much in Vegas to make it a locale caricature!!).
It may be of interest that Jem Cohen lists Ben Katchor as one of his biggest influences, and even co-dedicated his wonderful film "Lost Book Found" to him (along with Walter Benjamin).
