Novels? There's only one Latin novel extant, and I don't know of any others that are lost. Except for that one, all surviving novels are Greek.

Romans claimed satire as their own invention (Quintilian claimed "satura tota nostra est," "Satire is our own entirely" but I think Aristophanes comes close to satire if not entirely making it there).

about encyclopedias, the only things I can think of in Latin are Pliny and maybe Gellius?

This is not to say that Romans didn't have cultural contributions to make, just that the two forms you mentioned don't seem to me to originate from Latin literature, and that maybe satire did (but what constitutes satire is really a matter of opinion).

Did the Greeks invent anything (culturally) or just ripoff the Phoenicians? The answer to both questions is no. More than any other language, Latin has had an influence on the languages of Europe. They built infrastructure that facilitated travel, brought sophisticated government to much of Europe and improbed other parts of te Ancient World. They were great lawgivers. A good deal of the world was influenced by Roman law. They were great builders and their influence can be seen today in many parts of the Western World like the Capitol (named after the Roman hill).
