The terms are a bit messed up, but the closest thing these are to a US organization is a presidential campaign policy working group. [1] These are the guys who basically act as advisors to the government's top politicians on issues that relate to technology.

Edit: They don't only manage the online presence of the political party. They are more detailed, coming up with policies and papers (presumably - none of these ever show up in public, oddly) [2]

[2] The head of the IT cell's LI profile - https://www.linkedin.com/in/argupta26

Ah like SPAD's (Special Advisors) are they considered temporary civil servants it seems odd that an unelected "advisor" is making policy and being quoted in the media though.

The ruling party, BJP, has a group of IT professionals managing their online presence. This, they call their "IT cell".
