Several years ago we replaced our RDBMS with a triple store. We are having one graph containing all the customers, as well as their assets and liabilities we manage (we discussed a lot about which design to choose and this turned out to be the best). Allowing our data to be accessed via LDP should not require us to split out data into many graphs.

So you would want a GET on one resource to return all the triples in the store? ( since you only have one graph )
How would you implement the creation of an LDPR by POSTing it to a LDPC? Do all the triples you posted also appear in 
this one unique graph? Do they all also appear in the created resource? Do both those resources end up containing the same
triples? If so you perhaps don't need an LDPC. You just need one LDPR to which you can send PATCHes to.
