As far as I know, "unendlich" is an adverb/adjective. And after bis
should come a noun.
I found
integrieren bis Unendlich
while I expected
integrieren bis Unendlichkeit
How is the first citation ok? Can someone explain?

Unendlich is used as a "number word" in mathematics like five or ninetynine
You also say Die Zahlen von eins bis fünf
, so you can also say Die Summe von fünf bis unendlich
.
The mathematical symbol ∞ is called Unendlich.
Actually I see no reason for a substantive there. The word unendlich is the appropriate number word on the same level as zero, one, pi and four (which are no substantives either). In German Unendlichkeit is the term for philosophy and religion and I find it quite appropriate, to have that separated.
Finally: yes, integrieren von 0 bis unendlich is fine (no reason for uppercase).

... no, not at all:
Bis morgen, bis hierher, bis dann, bis fünf, bis unendlich
where do you see nouns used here?
Nouns are used with bis + prep., e.g.
bis zum Ende, bis an die Kante, ...
Correct German would be "bis unendlich" and "bis zur/an die Unendlichkeit". Only the former is used in mathematics, consistent with other numeral words like "bis fünf" (and not "bis zur Fünf")
