Yen Press, Viz, Seven Seas, and Dark Horse list the age rating for each series/volume on their site. So does Rightstuf.
Viz doesn't- I've been on their site several times to try and look it up. You're right about Yen, Darkhorse and Seven Seas, though- Seven Seas is a little trickier to find those ratings listed!
And what Animegirl said about the rating. Some of the All Ages really aren't, because there's no universal standard for content ratings and each company polices their own titles. I can think of a few titles that are the reverse- where they're listed as for Teens or Older Teens but have virtually no objectionable content, such as Baby & Me, and the Aria series.
