I am sure that even if it is confirmed that the attack was successful not due to user error, but using some kind of wallet vulnerability, Electrum does not compensate for the losses to its users, as Nicehash did in a similar situation.
Electrum doesn't run a for-profit business. They don't make money on our use of their software, so there is no pool of funds from where you could get compensated. Their software is free, you don't pay any fees to them for the product you use. It's open-source software where each user is responsible for protecting their sensitive information.
