Just for extra reassurance, I also tested:

// main.ts
import * as tools from "./mod.ts";

tools.toolA1();

// main.ts
import * as tools from "./mod.ts";

tools.toolA1();

And it outputs the exact same JS file. I hope this is reassuring to the next person too!

If I chmod +x transpile.ts and then run it: ./transpile.ts, I get the following js file:

const toolA1 = ()=>{
    console.log("Tool 1");
};
toolA1();

const toolA1 = ()=>{
    console.log("Tool 1");
};
toolA1();

Demonstration:

// a.ts
export const toolA1 = () => {
    console.log("Tool 1");
};

export const toolA2 = () => {
    console.log("Tool A 2");
};

export const unusedFunctionA = () => {
    console.log("This will be tree-shaken A");
};

// a.ts
export const toolA1 = () => {
    console.log("Tool 1");
};

export const toolA2 = () => {
    console.log("Tool A 2");
};

export const unusedFunctionA = () => {
    console.log("This will be tree-shaken A");
};

// b.ts
export const toolB1 = () => {
    console.log("Tool B 1");
};

// b.ts
export const toolB1 = () => {
    console.log("Tool B 1");
};

// mod.ts
export * from "./a.ts";
export * from "./b.ts";

// mod.ts
export * from "./a.ts";
export * from "./b.ts";

// main.ts
import { toolA1 } from "./mod.ts";

toolA1();

// main.ts
import { toolA1 } from "./mod.ts";

toolA1();
