Could you not skip the event subtables and instead just do a search on the triggers table when an event happens, since you are registering specific events?

local addon = CreateFrame("Frame", "EscortEventAlert")

local triggers = {
	["<monster emote message>"] = true,
	["<monster say message>"] = true,
	["<monster whisper message>"] = true
}

addon:RegisterEvent("CHAT_MSG_MONSTER_EMOTE")
addon:RegisterEvent("CHAT_MSG_MONSTER_SAY")
addon:RegisterEvent("CHAT_MSG_MONSTER_WHISPER")

local function OnEvent(self, event, msg, monster)
	if triggers[msg] then
		PlaySound("RaidWarning")
		RaidWarningFrame:AddMessage(monster.." needs help")
	end
end

addon:SetScript("OnEvent", OnEvent)
