No unfotunately not afaik
I think I had created some lookup tables in the past but cannot find them anymore, sorry
Should have added them to the Wiki, damn

LibSets got the names (multi language) of the quest givers in LibSets.undauntedChestIds
but I had not added any constants for the quest givers. It's just 1, 2 and 3 for the chestIds ->

local undauntedChestIds = {
    ["de"] = {
        [1] = "Glirion der Rotbart",
        [2] = "Maj al-Ragath",
        [3] = "Urgarlag Häuptlingsfluch",
    },
    ["en"] = {
        [1] = "Glirion the Redbeard",
        [2] = "Maj al-Ragath",
        [3] = "Urgarlag Chief-bane",
    },
    ["fr"] = {
        [1] = "Glirion Barbe-Rousse",
        [2] = "Maj al-Ragath",
        [3] = "Urgalarg l'Èmasculatrice",
    },
    ["ru"] = {
        [1] = "Глирион Краснобородый",
        [2] = "Мадж аль-Рагат",
        [3] = "Ургарлаг Бич Вождей",
    },
    ["jp"] = {
        [1] = "赤髭グリリオン",
        [2] = "マジ・アルラガス",
        [3] = "族長殺しのウルガルラグ",
    },}
lib.undauntedChestIds = undauntedChestIds
