Fixed, Lester's WAR weights out to above 2
Fixed, Zobrist's WAR weights in below 1
Fixed on Redick and his WAR weighs in below 2
I'm not sure why there's any need to be vague. Lester's was 4.6, Zobrist was at 1.9(in 126 games, I have no idea where you're getting below 1 from) and Redick was at 2.5.

Correct on Keuchel but he was able to get that money despite having a 0.4 WAR and you say he was a year removed from winning the Cy Young?
That money? It's 9 million on a short term. That seems pretty reasonable, especially given his age and prior success.

..well then Edwin Encarnacion made the All Star team in 2016 and had a 2016 WAR of 3.8, finished 14th in league MVP voting. So what is that worth?
Well, leaving aside the fact that he was also 34 and some decline should be expected, that season was worth 3.8 wins. Which would have not changed the stakes for the Blue Jays no matter what they paid him and still wouldn't even if he were able to maintain that play, which he clearly hasn't.

Point is WAR is not the gold standard on deciding how much to spend on a player.
Cherry picked examples of one year of any number seems designed to be misleading. Zobrist, for instance, in the 3 years before his injured year was above 5.0 every year, a mark Edwin has only hit once in his career. Nobody gets signed on the basis of just one year, you take the wealth of information you have, including things like a player's age, and try to make a smart decision for the future.
But even then I think the Zobrist vs. Edwin thing is instructive. Zobrist(who signed for substantially less money than Edwin wanted despite being historically a significantly more valuable player) is the sort of player a team might be well served by if they've got enough talent already on the roster that he could push them over the edge and, indeed, he did have that one very good year for the Cubs where he helped them win the World Series.
If the Jays were meaningfully close to contention then signing older players to bad deals in the hopes that one or two good years might push you over the top is a decent enough strategy, however they weren't that close to contention after 2016(as we saw in 2017) and so it didn't make sense at the time.
