Though it doesn't clearly say if they left the 10th tier statue behind or the prototype, I think it was the prototype. No way Ainz would hand over 10th tier magic to anyone.

As for leaving anything at all, I think the reason was said in the vol. 6 epilogue. If they didn't leave something, the kingdom would have gone after the Eight Fingers. Since they kept quiet about the statue, they couldn't use it as a reason to go after them. If there was no statue, they would have gone after them and perhaps discovered Nazarick. Since Nazaick took control of the Eight Fingers.
