Southern Italians have no ancient Greek ancestry

Those Bronze Age Sicilians are much younger than 4000 years. They lived immediately before the Greek colonization of Sicily:

Sample = age according to the link above

I3876 = C14 dated to 1071-902 calBCE
I10372 = 1374-1131 calBCE (3005±20 BP)
I10373 = 1450-1150 BCE (the son of I3878)
I3878 = 1379-1196 calBCE (3015±20 BP)
I3125 = 1612-1506 calBCE (3275±20 BP)
I4109 = 1631-1509 calBCE (3300±25 BP)
I7796 = 1879-1691 calBCE (3455±25 BP)
I3124 = 1948-1777 calBCE (3545±20 BP)

^^^
You wrote that Greek started migrating to Sicily in the 8th century BC, so I3876 is not much older than the arrival of Greeks:

The ethno-genesis of southern Italians is very recent, so you can also throw away all the narrative of remote connections and so on. The Roman-age Levantine contribution is much greater than the ancient Greek one, but it makes no sense to say that the latter is less than 0.1%. Instead, it is more realistic to say that the ancient Greek contribution is there, but it is not a predominant part being less than 25% in the average southern Italian.

"To quantify the original demographic impact of the Greek settlers inferable from present-day Y chromosome variability, we explored two main census scenarios using a simulation-based approach. In the first scenario, high count, we based our model on the demographic estimates of Beloch, 18, 19 who suggested a census size of 1.35 million people for Sicily and of 3 million for Greece at the time of the Hellenic colonization in the Archaic Period. In the second scenario, low count, we modeled population size estimates that were smaller by an order of magnitude. 21 Nevertheless, the two scenarios have similar source / recipient effective size ratios (S / R). If we assume that the proportions of past Sicilian, Euboean and Peloponnese census and male (and female) effective population sizes is one-sixth of the current census size, we estimate a S / R of 3.65 for the high-count model and a S / R of 3.75 for the low-count model. Simulation results are reported on Figure 3 and Supplementary Table S8. When Considering Y-STR haplotypes, the observed DHS value between Euboea and East Sicily (0.5353) is compatible with an effective number of migrants ranging between 500 and 5000, clearly rejecting larger contributions (10 000), irrespective of the scenario considered. The DHS value obtained for hypervariable region I haplotypes (0.5995) supports an effective number of migrants between 500 and 1000, with larger contributions clearly excluded. When the NRY- and mtDNA-based estimates are paired according to the demographic model, the male-to-female migrant ratio ranged between 1: 1 and 2: 1 under a population growth model and between 2: 1 and 10: 1 under a constant population size model. "

The impact of the ancient Greeks must be quantified with autosomal DNA, not with conjectures or Y chromosome.

Brother, you don't know what you're talking about. The Sicilians of that period were only 6% CHG and the Levantine component was almost completely missing.

Don't see how can you prove that they don't. I'm pretty sure they do have significant ancient Greek ancestry.

It's about the same and both are only slightly above 10%. Main components are Anatolian and Italo-Celtic. Moreover using a southern less Kavkaz shifted Anatolian source completely eliminates the Levantine admixture. That doesn't work for truly semitic admixed populations like the Jews.
