I read that Kashiram stitched a green kafni for Maharaj and then refused to give him Dakshina, which is why Maharaj had robbers attack him. Is this accurate?

This summary misrepresents the events described in Chapter 0. It is true that Kashiram stitched a green kafni for Maharaj. However, far from refusing to give Dakshina, he was so eager for Maharaj to accept it that he would feel bad and cry if Maharaj didn't take it one day. To cure the pride that grew from this, Maharaj engineered a separate situation where he demanded excessive Dakshina until Kashiram's funds were depleted. The encounter with the Bhil robbers was a completely different incident that occurred while Kashiram was returning from a market and was not orchestrated by Maharaj.
