Though Azem's pronouns in the time of the World Unsundered match your character's pronouns, your WoL as they are in the present did not exist at the time of the sundering, and Venat did not sunder your WoL. There are many cases where this and other games would benefit from inclusive language; this might not be one of them.
When we discuss archaic texts that overgeneralize humanity to "man", we can acknowledge that those times were not conscious to a need for inclusive language, but we wouldn't change the quote to use a more inclusive term if the context was, "The original speaker said....." Venat is represented here at the time she, an Ancient, said a thing, and the language of the Ancients overgeneralized humanity to "man".
An argument could maybe be made that the Echo's alltongue power would translate "man" in your WoL's head to a gender neutral term as your WoL would understand it; but then we have to determine what exactly the extent of the WoL's experiences during the return trip through the time rift was. Which is to say, such an argument might be overthinking the matter.
