Yes, and other matters
So, before we move on, are you ceding the point that the scriptures teach the trinity?
I'm not up to speed on the JW's issues concerning "God" vs "Jehovah." If, perhaps, they think there's something immoral about using one over the other, then I suppose it would be on them to explain it from scripture. Though I don't know if they claim to hold to any of the
solas, so it may be moot. Double moot, since they don't hold to scripture, to begin with (having concocted an altered translation).
If you mean, how do we correct them on issues of translation? I don't think
sola scriptura is meant to cover such things. Sola scriptura, as I understand it, states that "all truth necessary for our salvation and spiritual life is taught either explicitly or implicitly in Scripture."* I don't think the proper translation or transmission of texts falls under the rubric of things pertaining to salvation or spiritual life. The more penetrating question I've heard posed by a Catholic, is "how can Protestants say '
sola scriptura,' and disregard the church or tradition, when the canon was handed down by the church's tradition?" To both objections, I'd have to point out that I don't think
sola scriptura was meant to apply before
scriptura. Before we can limit our authority to the scriptures, we must have scriptures to begin with. I don't think
sola scriptura was meant to suggest the idea that Christians in Macedonia, in the mid-first-century, could only rely on scriptures that had not reached them yet.
I'm sure, in the past 499 years, others have explained this more cogently. Also, I'm assuming the most exclusive understanding of sola scriptura. There are other, more inclusive, notions within Protestantism/Evangelicalism.
In the Anglican tradition, Sacred Scripture, tradition, and reason form the Anglican triad or "three-legged stool", formulated by the Anglican theologian Richard Hooker.[4][31] "Building on the Anglican theological tradition, Wesley added a fourth emphasis, experience. The resulting four components or "sides" of the [Wesleyan] quadrilateral are (1) Scripture, (2) tradition, (3) reason, and (4) experience.

8 See to it that no one takes you captive by philosophy and empty deceit, according to human tradition, according to the elemental spirits[a] of the world, and not according to Christ.
Colossians 2.8 - a Biblical admonition to put Christ above tradition. Christ is "the Living Word."
