We know that, electronegative nature decreases down the group, so Li will have higher electronegative character than other elements of the group, and also it has very small size the lithium halides become covalent in nature.
It is because, the small size of Li+ cation will have the maximum tendency to withdraw electrons from anions and so it polarizes the bond and in this process, it distorts the electron clouds of anions which neutralizes some of the charge, and their increases a covalent character.
The Fajan's rule explains that smaller the size of atom higher will be polarizing capacity and so the covalent character will be larger.
So the Lithium halides become partially covalent in nature.
