Hi Darcy,

You don't need an Automator action or AppleScript to update all 
podcast feeds.  There's a keyboard shortcut that will make iTunes
resync all RSS feeds:

Command+Option+Right Bracket will cause all your podcast feeds to
resync at once.  This command also has the side effect of opening
all podcast folders 

Resyncing the podcast feeds is more than updating them, though it
also works to update your podcast feeds

1) It refreshes all the information on podcast episodes - this is most 
useful when a wrong or defective episode was posted.  If you downloaded
it, but found that it was a repeat of the last episode, for example, you 
can't get the corrected episode for your subscription by updating the
feed, even if you deleted the incorrect entry, because as far as iTunes
is concerned, you already downloaded the latest episode.

2) It also gives you a list of every available podcast episode on the 
feed -- not just from the point you started your subscription.  (It doesn't
download these episodes, but just puts an entry in the Songs Outline
list for the podcast so that you can find out the description of that
episode, and download it if you choose  to. 

If you just want to open all podcast folders at once without resyncing
the feed, use Command+Right Bracket.    And to close all podcast
folders at once, use Command+Left Bracket.

This was described in a Mac OS X hints column:
