Start by locating the Rust module shown in the logs, taiko_preconf_avs_node::ethereum_l1::monitor_transaction, and trace how an "insufficient funds" response is handled after the transaction watcher timeout. Check the surrounding preconfirmation flow and its tests, if present. Done means this balance failure causes preconfirmation to stop instead of continuing to process later slots.
