Section 3.3.2 says:

For messages that do not include a payload body, the Content-Length
indicates the size of the selected representation (Section 3 of
[RFC7231]).

It should say:

For outbound messages that do not include a payload body, the
Content-Length indicates the size of the selected representation
(Section 3 of [RFC7231]).

Notes:

Assuming my interpretation is correct, this phrase as-is is a little confusing given the next paragraphs states:

"A user agent SHOULD NOT send a Content-Length header field when the request message does not contain a payload body and the method semantics do not anticipate such a body."

The former is ambiguous, the latter explicit.
--VERIFIER NOTES--
The sentence in question has to be taken in context with the entire paragraph, with the rest of the section, and with the understand that it's only a summary. The details are provided in the rest of the section and in Section 3.3.3.
