Lilith is or never was a demon, her enemies made her into one. One group of people got on the older lies and kept it going.
I personally do not call her lilith, but Lady Wind.
As “Lady Wind” she may be associated with the figure of the Akkadian demon “Lil-itu”, thought to have been the origin of the Hebrew Lilith legend.
Creatures resembling Lilith are first mentioned in the Mesopotamian mythology, however they do not take the shape of the characters from subsequent Jewish legends yet. While researching the Epic of Gilgamesh Samuel Noah Kramer studied the text of Twelfth Tablet which was not originally included in the poem. What he found there was the story of Inanna who planted the huluppu tree (most probably a willow) in her garden in Uruk so that she could make a throne for herself from its wood. However, when she came back after ten years to cut the tree, it turned out to be inhabited: a serpent was living in its base, a Zu bird (a huge bird with the head of a lion) had the nest with its young in the crown and ki-sikil-lil-la-ke found the home in its trunk. According to the tablet Gilgamesh, asked by Inanna, has smitten the serpent, made the Zu bird fly away to the mountains with its young and ki-sikil-lil-la-ke destroyed her house and fled to the forest. There is not enough evidence to identify Lilith with ki-sikil-lil-la-ke, in fact modern scholars reject this connection. The only thing that can be determined with high probability is the analysis of the tree spirit’s name: ki-sikil means ‘sacred place’, lil is ‘spirit’ and il-la-ke can be either ‘water spirit’ or an owl. According to one of the Sumerian texts, Lilitu is Inanna’s handmaiden, a beautiful prostitute whom the goddess sends to the streets so that she seduce men there.
Moreover, in the texts of incantations from Nippur in Babylon dated back to around 600 BC there is a mention of vardat lilitu meaning a female spirit connected with storms and winds; the word lili itself was associated with magic and demons. According to some hypotheses, the Sumerians and the Akkadians, the native inhabitants of Mesopotamia, were bilingual and their deities became syncretised, in this case in the Sumerian language the spirit was named ki-sikil-lil-la-ke while for the Akkadians the name of the same spirit was Ardat-lili (Ardatû). Lilitu were also present in the myths of Assyrians, the heirs of the Sumerian and the Akkadians, as the demons hunting for women and children associated with lions, deserts, storms and diseases. Originally they were linked to the wind and storms and then to the night and copulating with people while they were sleeping; lilitu were hostile towards families, seduced men (it was believed that sick men were possessed by lilitu), caused infertility, miscarriages, complications during delivery and death of babies. Prostitutes were also called ardatû.
