In addition to what others have pointed out, many of these aren't actually missing from traditional dictionaries: they're just inflected differently. So your example lists phrases like "operating systems", "immune systems" and "solar systems" as missing from traditional dictionaries, but at least the online OED and M-W have "operating system", "immune system" and "solar system" in them. It's just that your script is apparently listing the plural as a separate phrase.

On languages other than English: in general, different languages do word division very differently. At least in German and Dutch, many of those phrasal verbs are separable, meaning that they are one word in the infinitive but are multiple words in the present tense. So for example, where in English you would say "I log in to the website", in Dutch it would be "Ik log in op de website". "Log in" is two words in both cases, but in Dutch it's the separated form of the single-word separable verb inloggen ("I must log in now" = "Ik moet nu inloggen"). The verb is indeed separable in that the two words often don't end up next to each other: "I log in quickly" = "Ik log snel in".

Dutch, like German, has lots of compounds. But there are also agglutinative languages, which have even more complex compound words, perhaps comprising a whole sentence in another language. Eg (from Wikipedia) Turkish "evlerinizdenmiş" = "(he/she/it) was (apparently/said to be) from your houses" or Plains Cree "paehtāwāēwesew" = "he is heard by higher powers"; and these aren't corner cases, that's how the language works.
