I doubt there would be a transcript. It wasn't a trial, it was a mentions hearing, which is purely administrative process, setting dates for the next hearing and working out where it fits in the legal system.
It's quite possible someone from the WTS side made a reference to the FDS being a theological arrangement -- they are happy to use the words "theolological" and "denomination" when they're forced to in a legal setting but avoid using them in their literature because it demeans their sense of divine appointment.
However I don't for a moment think that they would have referred to it as an imaginary friend. The rest of the quote referring to "a well placed mind placement" etc is clearly the thinking of someone who is an opponent of the WTS, possibly lifted from a web forum.
