Don't count on DL giving you a hotel if you misconnect.

Are you sure these are the only possible DL connections from BDL to LAX on DL? There are more than two DL flights daily from BDL [IIRC the current schedule has three or four BDL-MSP nonstops every day], and getting from any DL hub (including ATL, although there's a slight chance that ATL wouldn't be a legal routing) to LAX should be easy.
