To broadcast a transaction, you need it to be in raw hex format.

However, sweeping like that requires entering the private key on an online PC. Electrum currently does not support creating a watch-only wallet for a P2PK script, which would be necessary to offline sign a tx. Considering it is a lot of money, if you have the WIF key, you should probably just use Bitcoin Core. Create a wallet there using the WIF key on an offline PC. Export output script descriptors and use those to create a watch-only wallet on an online PC, then create an unsigned tx on the online PC, export that and sign it on the offline PC, then broadcast the signed tx on the online PC.
