I don't see what the problem is here. Just make up your own slimy, tentacled beasties with with names that contain too much punctuation and too few vowels. Problem solved.
Here's one for free:
Great K'Koovl, the drooling god. Imprisoned in a crystal universe beyond our own by the creatures who serve it. Great K'Koovl is forbidden from manifesting his physical presence in our dimension, however, he can possess the body of a willing person for a short time, and, during a total eclipse, it is said that certain sensitive people can hear him sweetly singing, singing, singing. To hear his melodic yet utterly alien song is to go insane.
See? It's easy. Lovecraft's style and story content is pretty easy to mimic because it's so well known. Just don't rip off any specific elements from Lovecraft's stories. Don't mention Arkham, don't use any characters from the books, don't have people turning slowly into fish creatures, don't even use the Necronomicon (invent your own evil-sounding book, if necessary), etc. Use your imagination a little and you'll do just fine. Good luck with your game.
