Bonjour Stewart,
In this sentence, the subject of ‘permettent’ is 'qui' (= referring to ‘outils sophistiqués’) and therefore ‘permettre’ is conjugated in the third person of the plural form.
‘nous’ is an indirect object pronoun of the verb ‘permettre’ (= permettre à qqun de faire). See link: direct-indirect-object-pronouns
I hope this is helpful.

Answer

The subject of the clause isn't nous (that's the COI), it is qui. And whatever qui relates to in the main clause (which you didn't show) must be 3rd person plural.
