That isn't good either. Not because you aren't using Ledger Live, but because you are using an outdated Bitcoin application on your Ledger HW. It might have bugs or vulnerabilities that you aren't protected from. The newer versions could have stability and speed improvements you can't benefit from. You will also not be able to take advantage of things like Taproot in the future unless you update your Ledger bitcoin app.
The last update I did was about 3 months ago, so it already includes these things. Either way, in the future it will be to migrate to another HW wallet. Until then I can continue to use it with some peace of mind and without major complications.
