Yes there are. Who you think pays all of these think tanks and so on. These think thanks that are centeral left often have much more money then the libertarian think thanks operate on. George Soros does many of the same thing as the Kochs.

The strategy is not unique to the Kochs by far, even if the intellectual have an absurd obsession with Kochs and see them as 100x more powerful then they actually are while they ignore 100s of other people who fund think tanks and policy initiatives and so on.
