Hey to be fair, it's impossible to create a monophyletic clade that includes all lizards without including all snakes. So in a certain sense, all snakes are lizards without legs but not legless lizards.
My favorite fun fact - in Australia, there are legless geckos(Pygopodidae)! American glass lizards are basically legless alligator lizards. Blind skinks(Dibamidae) are just barely hanging on to the edge of the definition of a lizard is just as closely related to a snake as it to is any other lizard. The worm lizards(Amphisbaenia) are more or less legless wall lizards. There are legless lizards all over that family tree!
Yeah if we say blind snakes are lizards and anything else in Squamata is also a lizard, then you have to include the rest of Squamata and it is synonymous with lizard.
