Not necessarily. "Killed" takes an agent argument, meaning that something or someone was the cause of the death. In the case of an OD, you can say the drugs killed, the person who made the drugs killed, the person who sold the drugs killed, etc.
The police did contribute to his death, at no fault of their own. They could have possibly done something to save him maybe if they magically knew everything... but they did contribute to Floyd's death.
