No, because an L2 rollup isn't a typical cloud server. It's a form of verifiable computation: the server does some computation, and after a while posts a cryptographic proof of the state changes to a more secure ledger (the L1). The benefit of this is that you get a high throughput system that inherits the same security guarantees as the L1. This is why something like a ZK rollup operator cannot "steal your funds" compared to something like a CEX operator.
