People said/wrote in the past that what NSA and other intelligence agencies did was to gather data and store the meta data. The actually traffic got processed for the meta data, and small amount of the traffic got sorted out and also stored.

I would suspect that today they also process the traffic for llms and thus store a bit more of the traffic as weight and biases. All that can be done distributed and to different degrees based on how much access they got and under what operational conditions.
