LOT departs from satellite 7 and uses the SAS lounge. You can certainly choose to use the LH lounge instead, which has far better food and beverage offerings, though it is worth noting that unlike the SAS lounge it is completely underground. The major issue is that you will need to go through security twice - first at satellite 6 to use the LH lounge and again at S7 to board your flight. The security folks may let you know that you are at the wrong satellite but will let you in.
Frankly, if you have time to spare, then skip the LH lounge and just head over to the Star Alliance Lounge in the main building, where you'll find significantly better amenities (despite low ceilings and no views per se.) You will have to go through passport control (leaving the Schengen zone) but that's typically better than going through security twice. Just in case, ask the checkin agent for a Star Alliance lounge invitation card - you won't need it to enter the lounge but it may be handy at passport control should you get questions.
