If the NSA created Bitcoin, why did the CIA need Gavin to brief them on what it was?

It's not the One-Time Pads (OTPs) themselves which are unbreakable. Instead, certain ciphers cannot be broken if the key is truly random. However, this does not mean that a One-Time Pad (OTP) is truly a one-time pad as a truly-random pad will have a likelihood of being truly-randomly generated again reversely proportional to its' length. What this means is if the length of the pad is 1 binary digit (bit), then the next pad has a 50% chance of being the same; if the length of the pad is 2 binary digits (bits), then the next pad has a 25% chance of being the same; and so on. The name One-Time Pad (OTP) is misleading. From this moment on, I shall call such devices Truly-Random Pads (TRPs) as true randomness is their significance.

However, true randomness does not exist. You see, all particles in existence are at a certain position. From that position, the laws of physics dictate their motion. Therefore, all events in space are preset at this moment. In order to determine and/or alter the future of an isolated system, one would have to reside outside of it. I have observed this in 1997 or 1998 when analyzing something beyond your wildest imagination – it is one of my PANDORA-grade projects; PANDORA designating that it should never be made as it converges towards a collapse of the space-time system we're in, with extinction event being a mild term for the outcome.
