-(이)라도 marks what is met as a minimum or a fallback rather than the ideal: 한 번이라도 만난 사람들 'people you've met even just once', 메타버스에서라도 만나서 'meeting even if only in a virtual world'. In captions it also does a joking exaggeration — 상어떼라도 만난 비주얼, 'he looks like he ran into a pack of sharks'. Plain -도 만나다 would only add 'also'; -(이)라도 carries the sense of settling for this much.
