Does the decision make this easier?
Realistically, the rate of fraud nationwide is actually really low and this database would just a waste of time for the states that pursue it. But by holding it off the courts would be doing more to cover the administration (by giving them a plausible excuse) than letting it proceed.
It reminds me of those police drug busts where they take a picture of all the drugs and it's just like a couple small bags, but they'll run the press release like "hundreds of lives saved!"
Acting like there are going to be millions of voters purged serves both party messages right now.
But I think another perspective is a more dangerous effort to chip away at state responsibility for the process and procedures of voting. Once this is owned or easily influenced by a national institution then a single-party state disguised as a republic becomes far simpler to implement.
The danger here being that our system has relied on decentralized states handling these tasks and thus has not created the guardrails necessary (if ever they could survive a unitary executive theory) to ensure fairness.

Why do we pursue murderers? There are not that many.
Either the law matters or it does not. Pick your own world to live in, but be consistent.
Okay.
Even if you know with high certainty that a million ballots are fraudulent it is effectively impossible to challenge them because the judicial capacity required to do so doesn't remotely exist. There are adversarial scenarios where someone dumps vast numbers of fraudulent ballots and those ballots cannot be contested.
State legislatures have historically been empowered to vote in place of the people if the vote becomes infeasible or unreliable. People voting in Federal elections is largely a 20th century invention; the old methods are still available.
