I recommend actually downloading the complaint and seeing the references about ETH. ETH is very much included in the complaint, see the details about staking, etc.
The phrasing is like
"This includes, but is not limited to, the units of each of the crypto asset securities further described below—with trading symbols SOL, ADA, MATIC, FIL, SAND, AXS, CHZ, FLOW, ICP, NEAR, VGX, DASH, and NEXO—(the “Crypto Asset Securities”)"
