No, it's exactly the opposite--f-strings are, roughly, eval (that is, unsanitary string concatenation that is presumptively an error in any nontrivial use) to t-strings which are just an alternative expression syntax, and do not even dereference their arguments.
Shooting any unsanitized input into your application is bad. template strings don't make this worse. any_func(attacker_provided) is even worse then any_func(t"{attacker_provided}") since in the later case you actually have reduced the attack surface to just strings.
