I agree to you, when it's in person. I think what your describing is mostly the beginning of an answer.

Just randoms "um" inbetween because your struggling to build sentences can get annoying both in person and online

Just sit there in silence whilst you cogitate.

Space fillers are sadly important for group settings where you need to finish a thought before someone interjects.

But hearing them from an interviewee drives me crazy, along with "sort of", "kind of", etc. I once counted all of the "sorta"s in an NPR interview, it was brutal.

"Ummm, I think I agree with this description" vs "I, think, umm, I agree with, umm, this description"

The first one indicates something along the lines of "thinking, please stand by". The second one is a struggle.
