You dont need to create the relationship explicitly. OrderManager, PaymentGroupManager, CommerceItemManager etc gives some method to support split payment groups and that will create the relationship.
For example, in case if you want to use half of the order amount to one Payment Group called PG1 and remaining to PG2, you can use the below approach.
OrderManager.addOrderAmountToPaymentGroup(Order, PG1.id (payment group id), amount), this method will create a relationship and assign the amount to that payment group.
Next, you need to set the remaining amount to PG2,
OrderManager.addRemainingItemAmountToPaymentGroup(Order, PG2.id), this will add the remaining amount to PG2 and create the relationship.
Similiar methods are available in the manager classes mentioned above, check API docs for details.
