Trump's rhetoric around illegal immigration has mostly been about how tons of them are violent criminals, about reducing fentanyl smuggling (that's overwhelmingly done by US citizens for obvious reasons, but whatever), "invasions", and gangs, no less so in this campaign than the last. Effects on the labor market get some attention, but nothing like those other aspects.
[EDIT] From the Trump campaign's "2024 GOP Platform" doc:
----
1. Secure the Border
Republicans will restore every Border Policy of the Trump administration and halt all releases of Illegal Aliens into the
interior. We will complete the Border Wall, shift massive portions of Federal Law Enforcement to Immigration Enforcement,
and use advanced technology to monitor and secure the Border. We will use all resources needed to stop the Invasion—
including moving thousands of Troops currently stationed overseas to our own Southern Border. We will deploy the U.S.
Navy to impose a full Fentanyl Blockade on the waters of our Region—boarding and inspecting ships to look for fentanyl and
fentanyl precursors. Before we defend the Borders of Foreign Countries, we must first secure the Border of our Country.
2. Enforce Immigration Laws
Republicans will strengthen ICE, increase penalties for illegal entry and overstaying Visas, and reinstate “Remain in
Mexico” and other Policies that helped reduce Illegal Immigration by historic lows in President Trump’s first term. We will
also invoke the Alien Enemies Act to remove all known or suspected gang members, drug dealers, or cartel members from
the United States, ending the scourge of Illegal Alien gang violence once and for all. We will bring back the Travel Ban, and
use Title 42 to end the child trafficking crisis by returning all trafficked children to their families in their Home Countries
immediately.
3. Begin Largest Deportation Program in American History
President Trump and Republicans will reverse the Democrats’ destructive Open Borders Policies that have allowed criminal
gangs and Illegal Aliens from around the World to roam the United States without consequences. The Republican Party is
committed to sending Illegal Aliens back home and removing those who have violated our Laws.
4. Strict Vetting
Republicans will use existing Federal Law to keep foreign Christian-hating Communists, Marxists, and Socialists out of
America. Those who join our Country must love our Country. We will use extreme vetting to ensure that jihadists and jihadist
sympathizers are not admitted.
5. Stop Sanctuary Cities
Republicans will cut federal Funding to sanctuary jurisdictions that release dangerous Illegal Alien criminals onto our
streets, rather than handing them over to ICE. We will require local cooperation with Federal Immigration Enforcement.
6. Ensure Our Legal Immigration System Puts American Workers First
Republicans will prioritize Merit-based immigration, ensuring those admitted to our Country contribute positively to our
Society and Economy, and never become a drain on Public Resources. We will end Chain Migration, and put American
Workers first!

This basically fits with his proxies' rhetoric on e.g. Fox News, and his points at rallies: a little about the jobs aspect, but most of it's about how dangerous illegal immigrants are.
