I wonder if there's any legal precedent for other "not fully human intelligence" property that escapes containment and causes damage to a third party without any active malice, but nonetheless damage was caused. For example:

A. You own a large amount of cattle on a ranch.

B. Cattle are property. They're not human level of sentience, but people agree that cattle are capable of autonomous actions and going places and doing things based on their own instincts and nature.

C. Your cattle bust out of a fence on your ranch and damage something belonging to your neighbor. Let's say for the sake of an example of something cattle are known to do, they go spend a whole day rubbing up against your neighbor's car and severely scratch it and mess up the paint job on it.

D. You didn't instruct or train the cattle to cause damage, and the cattle have no actively malicious intent of their own, but nonetheless damage was caused.

Further theoretical: Your cattle wander into a major highway and cause a car wreck, the local sheriff's department is called out as part of the chaos and has to shoot some of them to put down the wounded beasts.
