In the spirit of Pareidolic icons, all that matters is that patterns can be recognized as language, those patterns have real and actual meaning, and they can be constructed procedurally to create a wide variety of patterns so that any species you encounter can communicate any idea.
Some actual Alien speech
A different kind of alien speech

I haven't played any of the space games that LT appears to be a sequal too, so I have no nostalgia attached to chatter. Maybe I don't know what I'm missing, but as far as procedural audio communications goes, meaningful clicks, chirps, whistles, squeaks, growls, rumbles, with pitch changes, repeats, speed changes, tone changes, reverberations, shifts, fugues, and so on could go a rather long way to create a real sense of atmosphere, profoundly alien, yet if you give it time to learn the differences that each race uses, you can really understand that 6 rapid clicks in a high pitch, as a growl grows in volume and changes tone, followed by 2 whistles, one short and high pitch, one long and lower pitch really means that there is a wormhole about 3000 km beyond the planet Jarbunthis in the direction away from the star.
This is only an initial idea, not given much thought, If anyone thinks it deserves more development, I can do so.
Challenging your assumptions is good for your health, good for your business, and good for your future. Stay skeptical but never undervalue the importance of a new and unfamiliar perspective.
