Enhanced Steam links to ITAD for its information, so whatever ES gives you, ITAD will also have.
Of course, ITAD regularly skips listing certain bundles, so checking Salenauts as well gives a good second perspective- though even there, it's likely a bundle or two will slip through (as occasional Groupees [Greenlight] bundles are rather prone to do).

Enhanced steam takes info from isthereanydeal.com The blue bar at the top is where you input the game name :P

Click on the game to open the pop up window. At the bottom of the "info" tab, there is "This game has been included in following Specials". That's the list of the bundles. If there is no such list, the game was never in a bundle (or isthereanydeal didn't register it).
