After testing your code on https://codepen.io/pen/ (which i recommend you to use for quick frontend stuff), I come up to the following solution :

var inputEl=document.querySelector("#input-bar");
var addBtnEl=document.querySelector("#btn");
var ulEl=document.querySelector("#output-line");
// var list=document.querySelector(".list");
console.log(inputEl);
let savedIn=[];

function f() {
  savedIn.push(inputEl.value);
  for(let i=0;i<savedIn.length;i++){
    var sample=`<li class="list">${savedIn[i]}</li><button class="tick"><span id="tick-span">&#10003;</span></button><br>`;
    console.log("in for");
  }
  ulEl.innerHTML+=sample;
}
function g() {
  var tickbtn = document.getElementsByClassName("tick"); 
  console.log(tickbtn[0]);
}

<input type="text" id="input-bar">
<button id="btn" onclick="f(); g()">Click</button>
<div id="output-line"></div>

Like that the output won't be undefined anymore ; it will display the first button (tickbtn[0]). And as I told you above in the comments section, it's preferably to not use event listeners in this situation. For any other problem, do not hesitate.
