Correct me if I'm wrong, but aren't the lowercase Greek letters all "italic" in both the Hershey and Truetype fonts that ship with IDL?
So couldn't you just use the !M to switch to the symbol font, then use "q" to insert the theta?
In new graphics, this would look like either one of the following:
p = plot(/test, title='Abc $\theta$ def')
p = plot(/test, title='Abc !Mq def')
The syntax in either DG or CG would be similar.
Cheers,

You can obviously make italic versions of Postscript fonts,
including the Symbol font, which is used to create Greek
characters:
Set_Plot, 'PS'
Device, /Italic, /Symbol
But, there is no way in IDL that I know of to switch
from an non-italic to italic and back to non-italic
font inside a text string. So, if you wanted an italic
theta and non-italic text otherwise, you would have to
divide the text string into italic and non-italic parts
and write them separately.
Seems like a lot of work for very little benefit
to me. :-)
Cheers,
David

I think you are probably going to have to find
an italicized Greek font somewhere...
