Well you have to weigh the risks. A typo versus the risk of three (instead of two) compromised devices/software needed to steel your assets. If you make a setup like this (2-of-3, or 3-of-3). I suppose you test it before you use it. Like delete everything and recover it from backup seeds. So that way you know you don't have a typo. Did you have a typo in your passphrase? You could still try. It shouldn't be that difficult to recover.
