The accounts shown when connecting your Trezor, are the accounts associated with the seed of your Trezor.
I do know that in some cases, certain Ethereum addresses are considered as “legacy”. Metamask has a specific feature for this when connecting the hardware wallet.
Is this true for you?
If not, the Axie content HAS to be in those multiple Ethereum (ronin) addresses you mentioned. If it’s a legacy address, it’s further down the tree.
P.s.: No, I’m not Trezor support.
