Lukas - what you want, as Tom has already said, is a Linux watchdog process to monitor if weewx is still running. If weewx is running the modules it calls will function as expected - or there will be a log error message. Log error messages can be detected by standard Linux processes also.
Weewx is designed to retry things in the event of most recoverable errors, and to log messages when problems are found. These messages are detectable. The time of the last archive record can always be determnined by a simple sql program, and appropriate action taken - even rebooting the rpi if necessary The weewx alarm process is for something which HAS happened, rather than something which has not!! The most likely cause of problems will be the weather station itself or the rpi itself - and it is unlikely there will be a bug in weewx - it is very robustly designed. The standard webpages also include the time of generation - so receiving systems have a means of checking the 'newness' of pages.
