Maybe. Python is under an MIT-like license, so you're fine, but if it were under e.g. the GPL you could still look to see if they have some form of runtime exception as GCC does. In any case it's rare for a company that's not well-established to care more about licensing that technical merit (and even any that do, the typical approach is to ask to buy a separate license if possible), and it's also rare that a company would use such a tool as this (created as a hackday project, in Ocaml, according to the author) rather than finding an alternative that meets their licensing criteria or just developing it in-house since it's not that big a tool and lacks a lot of useful capabilities like piping.
