I've got two adventures available where there is no supposition of violence by the PCs, but I'm not sure if that qualifies. At any rate they're good adventures; these days I always design without such presumptions; there are no pre-planned "fight scenes" in my work since I left the industry years ago.
(That said, neither were created explicitly for the jam, so that may make them inappropriate for it)
I think I'd best not, then. My adventures are nonviolent because they're high-trust (which means, in part, the adventures presume no vector of solution to the problems presented, and doesn't use problems where a given solution is optimal, so there's never an advantage to solving problems violently, so PCs almost never do), but maybe if I have some spare time I'll whip something up explicitly for the jam.
