Degoogling is not deblobbing and Lineage or /e/ use plenty of closed source software during runtime. The top parent and DivestOS author really is deblobbing* to some degree, but forks of LineageOS that introduce measures of "degoogling" hold onto vendor firmware blobs on androids /vendor partition for functionality. Those aren't known for connecting to the Google hivemind though.

My interpretation of the term degoogling fits the second part of your sentence, "getting away from online services": it is user agency in what network connections can occur, so either by default or optionally users can stop any signaling coming from the device they use. They don't have that freedom with the software the device came with.
