The phrase za osnovu i vtsilomu is a common piece of Ukrainian bureaucratic language, roughly meaning taken as a basis and in general overall. Clips built around formal filler like this spread on soundboards because the wording is instantly recognisable to Ukrainian speakers and sounds comically empty out of context. It has become a shorthand reaction for political talk, long winded explanations and any statement that tries to sound authoritative, and its short spoken format makes it easy to share in chats, streams and short video edits.
