No matter how many Sybils a person creates, the total debt owed to them

there's no advantage in creating Sybils. It's not impossible - it's just
pointless.
But sybils will report that a sybil pays his debts, thereby encouraging
non sybils to erroneously grant him credit.
Each peer maintains its own safe credit margins for other peers based on
the history of services exchanged with those peers. There's no way for a
third peer to cause the first peer to exceed its safe credit margin for
the second peer, even if the second and third peers are Sybils.
The second and third peers can assign each other arbitrarily large
credit margins, but when the first peer looks for a cycle, the amount of
credit added to the links of the cycle will be limited by the lowest
safe credit margin on any link (last paragraph of section V).
So the algorithm for assigning credit can be paraphrased "Don't take
anyone's word for it"
