Need Sprinkler Cracked PVC Pipe Repair Suggestions
The usually ways to introduce flexibility (both in terms of angles and actual movement) involve adding more elbows and more pipe. I'd take off the broken elbow, add a new elbow that turns to horizontal (toward the camera in this view). Add two new elbows to bring the pipe back to the tee in any convenient manner. You may need to rework more than that because there's no spare pipe at the tee. 

A few more elbows are unlikely to reduce flow enough to be a concern unless flow is already an issue, or nearly so.
