No founder, proclamation, registry filing or launch announcement for National Alice Day exists in any source located. Its earliest trace anywhere in the Internet Archive's record is a listing captured on 30 September 2022, which dates the day's circulation rather than its founding.
Carroll gets the spread, not the name
The name became popular in France and England in the 12th century and stayed among the most common names in England until the 16th century. Then it declined, and did not come back until the 1800s. In 1865 Lewis Carroll published "Alice's Adventures in Wonderland".
Sweden's Institute for Language and Folklore says the book certainly contributed to the name's spread. The book did not invent it. Alice had been current in England for roughly seven centuries by the time Carroll wrote a word of it.
