I would follow aysg76's comment, better convert all different cryptos to Bitcoin or I would say Ether is fine too, plenty self custody wallets available, Metamask being obvious choice.
However, it's usually target for malevolent actors, better set it up yourself, give them seed phrase and advise to hold it securely rather than using wallet itself.
From time to time, I still receive warnings from Metamask over my unverified wallet lol.
But for the sake of security, a hardware wallet is still a sound choice. They might even appreciate/ remember it's not something that costs a penny or two, or is free.
