I believe so. The official subtitle of the anime is the first bonafide English translation of the Touken Ranbu franchise (exciting~)... and it called Ishikirimaru an "ootachi". Historically, it's been translated a couple of different ways, but that's how it's spelled for Touken Ranbu.

We'll probably be seeing a couple of small changes like that as time goes on, though probably not too many
