While I am not aware of a tool to integrate with, you can look at the user agent and IP addresses the data is coming from. if there is a spike in a range of IP addresses or a certain browser/device type, it may be bot traffic. Check also the visit behaviour, as in the visit number from each unique visitor from this IP, or hits in each visit.
You can create a segment to filter out this traffic. As you identify more bots, you can keep modifying the segment
