I've been seriously considering no longer teaching wild edible classes due to the liability risks involved by such a scammer. It would be really easy for someone to fake an injury and sue me for everything.

Unfortunate, but a legitimate concern. Have you considered an umbrella liability policy?
When had house built, got $1M coverage (despite general and subs having appropriate coverages). An abundance of caution maybe, but you never know. Cost was reasonable. IIR, slightly more than $300 for 12 months (2002).
