Please see the following link for "MAJOR FOREIGN HOLDERS OF TREASURY SECURITIES (debt)":

It's an official document from the USA Treasury.
Libya is listed under Oil Exporters 3/, unfortunately though it doesn't give the specific debt amount for Libya.
I will provide a few other interesting things about the Libyan situation:
-The rebels created their own bank within weeks even before creating their own government
-The oil reserves in Libya are the largest in Africa
-The US and UK have been providing supplies to rebels for some time
-Qaddafi stated previously that he would provide future oil contracts only to China, India and Russia though he did make this statement after the uprising
-Qaddafi previously started a movement to refuse the US dollar and the euro and instead called on Arab & African countries to use a new currency called the gold dinar. Last year this idea was approved by many Arab countries and most African countries but was viewed badly by the USA and EU governments
-Libya's central bank is state owned and has nearly 144 tons of gold in its vaults
-Their central bank is also not a member bank of the Bank for International Settlements (BIS)
-Their oil industry is also nationalized
-All of this makes it much harder for foreign interests such as the BIS to interfere and screw over Libya's national economy to achieve their own ends
-While far from perfect, Libya's citizens enjoy free medical treatment that beats the US and other Western countries by a large margin,their education (including in abroad universities) is free, they get non-interest state loans, cars cost a lot less than in Europe, basics like petrol and bread cost next to nothing, there are no taxes for those who are engaged in agriculture, etc
I apologise for only mentioning the oil part and the debt previously though as there is much more at stake than that.
Back on topic: it also seems rather convinient that Osama's body has been gotten rid of so quickly; this means no possibility of future autopsies or investigations to find what what actually happened to his person.
