As I wrote as comment, typos on names are very very frequent, but to answer you:
No; the airline will transport you to destination, if you comply to rules. Failing such rules, there are no more obligation from your airline.
Missing passports, tickets, etc. are some reasons, but also health reason (also if you just fall in the stair on airport) (or drunken). Also governments could restrict you (or your airlines) to carry people in a certain zone. Natural disasters and wars also cancel obligation of your airlines. They doesn't need to provide you alternative transportation.
