Dotharl /doθarl/ is a Xaela term. This is a Dotharl-native shortening of a phrase, dota-hārl, roughly "those who do not fear death", involving the Xaela term /hārl/ relating to death. This is an exonym, which was loaned by the Dotharli for self-reference, acquiring the unique phoneme θ to the Dotharli dialect from an alternate version of the usual /th/ -> /s/ sandhi pattern.
An interesting Aldenardic cognate is Issom-Har, "Palace of the Dead" in Padjali.
(a)har (Amalj'aan: "perseverance", semantic unit 2, (a)lh 4) is not related (among other things due to Amalj'aan being a Turalic language that did not loan much from Eorzean ones), and neither is Thal, but West Ilsabardic garle (and similar forms), referring to a person with the inability to manipulate aether interestingly is, through the (somewhat inaccurate and metaphorical) idea of being aetherically 'dead'.
"dead" is on the Augurelt list of words that are least likely to be replaced across languages; the semantic shift in Ilsabardic is an exception, and the Padjali and Xaela terms convergently developed in a similar way (the original Allagan term was not *har-).
