As the deportee is in the US illegally, than anything they owned in the US would be part of their committing the crime of being in the US.

That's not really how it works. Forfeiture laws are (generally) tailored to required seized assets to be used in, or result from, the crime. That requires a level of causation that is typically more than just "but/for" - if you commit fraud on your car loan, and then use that car for a few years to commute to work, the government might be able to seize the car but they're not going to be able to seize your earnings from years of work on the grounds that the car allowed you to get there.

Plus, being present in the U.S. unlawfully is not a crime. It's a civil violation. Certain types of crossing into the U.S. are criminal rather than civil violations, but I doubt very many assets were acquired in connection with the act of crossing (not the later civil violation of remaining in the country).
