The properties of the ListView ItemStyles are bindable, however, the binding context that is passed there is the same as the one of the ListView, so this approach is not suitable for the scenario you have.
To accomplish conditional styling according to item's properties, you would need to use ItemStyle Selector, please go through the topic here: ListView: ItemStyle Selector
for more details on the exact approach.
Let me know if you have any additional questions on this.
