I would expect not some, but nearly all visitors fly into MLE, it is the main international airport in the Maldives. I think the only other real-ish international airport is way south.
Mahibadhoo Island, where Liberty Guest House is, is one of the islands that make up Ari Atoll. It looks like there is an airport on another island in the far south of Ari Atoll,
Maamingili (VAM). It may technically be an international airport, but appears to only have flights to/from Male, if that. (The runway wouldn't seem long enough for any long haul plane.) I suppose you could take a domestic flight from MLE to VAM, but Ari Atoll is big and that still leaves you pretty far from your final destination - actually surprisingly not much closer then you already were in Male. So you'd still need boat transport for the last leg, the difference being traveling along a slightly more sheltered atoll, vs. a more open water crossing which might be more weather dependant.
Water transportation is the major way of getting around in the Maldives, there are all sorts of ferries and speedboats. Male airport pretty much has a harbor instead of a taxi stand. (Note that Male airport is on it's own island, the actual city of Male is on a separate island.) I would contact the place you are staying to learn the best way to get there from Male airport. If you read the reviews, there are people talking about having done exactly that and how they got there. For example this comment a few months ago on Tripadvisor - "Before we left to Maldives I connected to Liberty guesthouse and I gave them flight information and asked, the easiest way to get to Mahibadhoo. They provide a guide who helped us from airport through Malé to the right speed boat. You don’t need to worry a thing. They will assist you with everything you need! "
