Could be. The first time I heard her call herself "child of Vlaakith", I took it completely literally and assumed she was a githyanki princess, since I knew nothing about the culture, but as I played the game more I came to the conclusion that it was just what githyanki call themselves. Maybe Larian is being super clever here.
The term giyanki means children of Gith and Gith was their original leader, later replaced by the first Vlaakith.
