I don't think she can even scratch Strada considering in his fight against Arthur who is a much better swordsman than Xenovia and with the strongest holy sword Calibrum, was on fighting a defensive battle against Strada and even when he went to the offense and teleported the tip of calibrum blade into Strada's blind spots, Strada  blocked each one of them. And in Strada case he can't damage Xenovia due to Avalon. Xenovia's duty will be to keep Strada busy, so then her teammates can go and fulfill whatever objective their game is about without the threat that is Strada.
