I guess I should have provided more context on my Roll20 question. I suspect that trusting it made my answer here incorrect, but I haven't had bandwidth to confirm that and rework the answer. rpg.stackexchange.com/a/211174/28580
@JoelHarmon In that case, yeah, the "Target" field seems to be original to Roll20 (presumably it exists for the purpose of API stuff/automations), so the fact that Roll20 specifies a target for each spell doesn't indicate anything with regard to the actual D&D 5e rules
