I'm still a little confused about your setup...
I had use the ledger nano to sync with the core using the experimental feature before, but to download over that 356gb for the bitcoin core to sync again on my new laptop is a hassle.
So, you were using the "experimental feature" in Ledger Live that syncs all the data through your local Bitcoin Core? If so, then any wallet.dat you have from your Bitcoin Core is probably empty/useless.
That feature is essentially a "privacy" feature... it means Ledger Live sends/receives it's data from your local node, rather than querying Ledger servers. It does not interact with the wallet.dat in any way.
Or are you referring to using the HWI module to use the Ledger with Bitcoin Core?
