SSSSS - Non-native Shamir Backup for seed phrases
In order to overcome possible shortcomings in other implementations Blockchain Commons have develped a standard and interoperable implementation of Shamir's Secret Sharing Scheme called SSKR and an accompanying library bc-sskr.

Tyoe of Shamir's Secret Sharing used in Ledger Recover?
I am very sure it won't be. Trezor and Keystone use SLIP-49 which has some shortcomings which were improved upon by SSKR.

Isn't a strong bip-39 passphrase enough?
SSKR is an improvement on SLIP-39. SSKR comes with a seedtoolcli. Tezor hardware wallets use SLIP-39 if you have one of those.

SSSSS - Non-native Shamir Backup for seed phrases
SLIP-0039 is not is not round-trip compatible with BIP-0039. SSKR / BCR-0011 is based on SLIP-0039 but improves upon it by adding this compatibility.

Splitting BIP-0039 Mnemonic
Please see the discussion here: https://www.reddit.com/r/ledgerwallet/comments/ibkls4/does_ledger_have_plans_to_implement_shamir_secret/ Maybe ask here if the Ledger developers nicely if they still plan to implement Shamir's Secret Sharing, If Ledger do not implement Shamir's Secret Sharing (e.g. SSKR) then maybe consider purchasing a Trezor which implements SLIP-39. Bear in mind that SLIP-39 is not round-trip compatible with BIP-39.

Getting MultiSig Protection with a Single Hardware Wallet - Could be a better solution.... For personal vault
Or use a single hardware wallet that implements a version of Shamir Secret Sharing (SSS) e.g. SSKR and store your steel share backups in multiple locations.
