Recursive descent is very common for parsers, and not quite the same as an LL(1) parser using recursion. Recursion depth can technically still be a problem in a lisp language, as not all recursive calls will be tail recursion. A recursive descent lexical analyzer isn't a "thing", although as other replies have pointed out, it's common in functional languages for a lexer to look a lot like a recursive descent parser for the "grammar" of tokens.
