Q: Siri was inspired by a government program that invested $150 million over five years.

Which noun does 'that' refer to? Siri or government program?

And I am also confused why not add 'was' ahead of 'invested'. Shouldn't use passive tense?
A: The subject of the sentence is Siri. It was inspired by a government program. What did the program do? It invested $150 million.

If the subject was the $150 million, then we would say "was invested" I will rewrite the sentence for you.

$150 million WAS INVESTED over 5 years by a government program that inspired Siri.
