Interesting point. I think this is more a question of counterfactual and Shapely values than VOI, as the concern is really a broader one. Similar how to if 4 interventions are all needed to save a life, you can’t just consider the counterfactual impact of the last one.
Most VOI analyses are highly simplified to get around issues like this.
