How can thorazine (chlorpromazine) be used for anxiety and and have anxiolytic properties if it induces akithesia which can lead lead to anxiety?

Dose dependent: Thorazine (chlorpromazine) wouldn't usually be my first choice for treating anxiety, though its use for that makes sense to me if used in low doses, since it dose have anxiolytic properties and is non-addicting. At low doses of thorazine, akathisia (restlessness) is less common than with Haldol (haloperidol) and several other medicines that tend to cause akathisia.
