It's not a mistake if it's verbatim. The [sic] is usually to show that the mistake isn't by the publisher but adding an additional space in a company name probably isn't egregious enough to warrant it.
Yes it is (and [sic] is specifically used for verbatim quotes[1]). Companies often take their style guides pretty seriously, so an extra space can be a big deal. But in any case, The New Yorker has extremely high AP standards, so that's why I'm surprised to see even such a slight mistake.
