We do have Task Charts which will create charts from any Saved Search that you can create, but we don’t have an extensive solution for generating reports. You can also use Task Analytics to create KPIs, but again that doesn’t sound like the solution you need.
If you could describe a sample report, then i might be able to recommend an approach. It will probably involve (as you have already suggested) an export of task data to an external system for reporting.
You could possibly start using the WmTaskclient from IS to iterate through the active tasks and generate an appropriate csv file.
