You mean you did put them there I guess or I misunderstood the first
part of your sentence.

I think it is a general rule of software design (I don't pretend to give
software design lessons though).

Are other modes likely to use those gud tooltip functions? If not,
they should not be put in the same module.

How id GUD different from other modes in this respect?

I fail to understand the problem from the the gud POV.
gud-specific tooltip code would only be loaded for anyone using gud anyway,
right?
