"Blend of Leo and Giovanni"
The name Leovanni is commonly a male name.
Leovanni is a modern American formation built from the Italian names Leo and Giovanni. The spelling drops the Gi- of Giovanni, so the name reads as Leo joined to -vanni. It first appears in United States birth records in 2007 and is not an established name in Italian or in any older naming tradition.
The pronunciation of Leovanni is lee-oh-VAH-nee.
